Operation
Installation
Low temperature burns:
The surface temperatures of some ICs on the printed circuit board
unit in the optical disk drive exceed 55°C while operating. Be
careful of low tenperature burns.
Loss of data
When the verify function is invalid, the write data quality is not
guaranteed. This mode should not be used for storing important
data. When using the mode for storing important data, a
preventive system measure such as file duplication is required.
1) Shock or vibration applied to the drive that exceeds the values
defined in the standard damage the drive. Use care when
unpacking.
2) Do not leave the drive in dirty or contaminated environments.
3) Since static discharge may destroy the CMOS devices in the
drive, pay attention to the following points after unpacking:
•Use an antistatic mat and wrist strap when handling the
drive.
•Hold the mounting frame when handling the drive. Do
not touch the PCA except when setting the switches.
4) When handling the drive, hold both sides of the mounting
frame. When touching other than both sides of the mounting

Installation
1) The user must not change the settings of terminals not
described in this section. The terminals must remain as set
when shipped
2) Do not change terminal settings when the power is on.
3) To strap setting terminals, use the jumper shipped with the
drive.
1) Make sure that the system power is off.
2) Do not connect or disconnect any cable when the power is on.
1) Be careful of the insertion directions of SCSI connectors. For
a system in which the terminating resistor power is supplied
via the SCSI cable, connecting connectors in the wrong
direction may cause the following:
The overcurrent protection fuse of the terminating resistor
power supply (SCSI device) may blow when power is turned
on.
The cable may burn if overcurrent protection is not provided.
2) Be careful of cable connector positions when connecting more
than one SCSI device. The SCSI device having the terminating
resitor must be connected to the end of the cable

CHAPTER 1GENERAL DESCRIPTION
1.1Features
1.2Drive Configuration
1.3System Configuration
This chapter describes the features and configuration of the optical disk drives.
The MCE3064SS/MCF3064SS (hereafter optical disk drive) are disks that maintain the compatibility and
intend high speed as the succeed drive of the the MCB3064SS/MCC3064SS.
The MCE3064SS/MCF3064SS are high-performance, 3.5-inch commutative rewritable optical disk
drives which incorporate an SCSI controller.
The interface connecting the MCE3064SS/MCF3064SS drives to the host system complies with the
Single-Ended SCSI-2 standard (ANSI X3T9.2/86-109: Small Computer System Interface-2).
The flexibility and expandability of the SCSI, the high performance of the MCE3064SS/MCF3064SS
optical disk drives, and the drives' commands set enable the user to construct high-reliability, highperformance disk subsystems with advanced functions and large-scale storage.
1.1Features
This section describes the following drive features:
• Performance
• Reliability
• Maintainability/operability
• Adaptability
• Interface
C156-E097-01EN1 - 1
1.1.1Performance
(1)Half-height standard 3.5-inch size (1-inch height)
The SCSI controller can be directly connected to the system SCSI bus. The controller meets the
specifications of the standard 1-inch height 3.5-inch fixed disk drive form factor.
(2)High-speed data transfer
• The rpm of the MCE3064SS disk medium is 4558 rpm and MCF3064SS disk medium is
3600 rpm.
• The disk drive is capable of 2.94 to 4.9 MB/sec (640 MB) high-speed data transfer.
Note:
The maximum data transfer rate in asynchronous transfer mode may be limited by the
initiator response time and SCSI bus cable length. The maximum data transfer rate through a
single-ended SCSI bus in synchronous transfer mode is limited also by the SCSI bus cable
length and transfer features.
(3)High-speed mean seek time
This drive features a linear voice-coil motor for high-speed head positioning. The average seek
time is the average of 1,000 random seeks and is 23 ms (128 MB, 230 MB, 540 MB, and 640
MB). (However, this does not include SCSI overhead or address check.)
(4)ISO standard (medium compatibility)
3.5-inch, cartridge-type, 128-MB, 230-MB, 540-MB, and 640-MB rewritable disks that comply
with the ISO standard can be used.
(5)Partial ROM/O-ROM optical media support
This drive can handle the partical ROM media, that means an ROM area is established as a part
of rewritable area, and O-ROM media.
(6)Direct-overwrite medium support
An optical disk drive can use an optic modulation direct-overwritten medium that does not read
an erase operation: 540-MB disk and 640-MB disk that comply with the ISO standard and 230MB disk.
1 - 2C156-E097-01EN
(7)Dust resistance
Through low power consumption, a cooling fan is rendered unnecessary in the optical disk drive,
and through the use of a film on the top and a metal plate on the bottom that excludes dust, a
simple, protective sealed construction is realized. This device is compliant with standards for use
in a Class 5 millions or lower dust environment.
(8)Lower power consumption
The power consumption of the optical disk drive is 4.9 W (at read/write). The minimum power
consumption is 0.5 W during power save.
(9)Automatic spindle stop function
If access is not made within a certain time, this function stops disk rotation to minimize dust
accumulation on the disk. This function can be set that time by the MODE SELECT command.
1.1.2Reliability
(1)Mean time between failure (MTBF)
This drive features a 120,000 hour MTBF.
(2)Error recovery
For the error depending on the optical disk drive, an recovery process is made by a suitable retry.
This drive features Reed-Solomon error correction (ECC) to assure error-free operation.
(3)Automatic allocation of alternate data blocks
This drive features a function which automatically allocates alternate data blocks to defective
data blocks detected while data is being read from or written to an optical disk.
1.1.3Maintainability/operability
(1)Diagnostic function
This drive has a diagnostic function to check optical disk drive operations. The diagnostic
function facilitates test and restoration.
C156-E097-01EN1 - 3
1.1.4Adaptability
(1)Wide operating environment
An LSI circuits reduce power consumption to 4.9 W (read/write). This drive features a wide
operating environment (drive envronment 5 to 45°C or larger than general office environment).
Dust particles are class 5 millions or less.
(2)Low noise and low vibration
This drive operates quietly (26 dBA or less) even during seek operations and will not degrade the
office environment. Rubber vibration isolators support the drive and minimize vibration.
(3)Vibration resistance (shock resistance)
Rubber vibration isolators protect the drive against external shock or vibration.
(4)Safety standards
• UL1950 (U.S.A., safety)
• CDRH class 1 (U.S.A., laser)
• CSA C22.2 No. 950 (Canada, safety)
• EN60950 (Europe, safety)
• EN60825 Class 1 (Europe, laser)
(5)Various radio wave standards
This optical disk device is installed in a host system, and meets the following standards:
• EN55022 class B, EN50082-1 (European wave standards)
• AS/NZS3548 class B (Australian wave standards)
1.1.5Interface
(1)SCSI-2
This drive supports the basic SCSI-2 specifications.
SCSI commands enable operation using logical block addresses that are independent of the
physical attributes of the drive, enabling software flexibility in terms of system expansion.
(2)Continuous block processing
Logical block addresses are used for data block addressing. Without consideration of the
physical attributes of track boundaries, the initiator can access data by specifying a block number
in logically continuous data space.
1 - 4C156-E097-01EN
(3)Mass storage data buffer
2,016 KB buffer is used to transfer data between the SCSI bus and disk. Since data is stored in
this buffer, the initiator can execute input-output processing effectively by using the high-speed
data transfer capability of the SCSI bus without regard to the data transfer rate of the optical disk
drive.
(4) Read-ahead cache feature
The read-ahead cache feature enables high-speed sequential data access as follows:
After executing a command to read data from the disk, the drive automatically reads the next
data block and stores it in the data buffer (pre-reading). If the next command requests this data,
the data is transferred from the buffer without another disk access.
(5) Write cache feature
When the host system issues the write command to the optical disk drive, a command complete
is usally responded after completion of the write and verify operations. By using the write cache
feature, a command complete is responded after completion of the data transfer to the data buffer
without waiting the completion of the write and verify operations then the write and verify
operations are made asychronouslly with the SCSI operation. Therefore, the apparent write
command processing time measured at the host system is reduced and the I/O performance of the
host system is improved.
The write cache teature is enabled or disabled by the setting swich.
Cautions When Using the Write Cache
When the write cache function is activated, a write error is reported
when the end status is indicated for a command different from and
subsequent to the specified command. If the initiator executes only an
error report command retry, the data in the block where the error
occurred will not be written correctly, so caution is necessary..
(6) Reserve and release functions
Reserve and release functions permit exclusive access control in multihost or multi-initiator
environments.
(7)Defective block slipping
When a disk is initialized, logical data blocks are reallocated in a physical sequence by slipping
defective data blocks. This enables high-speed continuous data block processing without
rotational delay due to defective data blocks.
C156-E097-01EN1 - 5
1.2Drive Configuration
1.2.1Drive model
Figures 1.1 to 1.3 show the MCE3064SS/MCF3064SS outer view.
The drive consists of mechanical sections, a fixed optics section, actuator, and a control circuit
section. The mechanical sections include the spindle motor, actuator section, bias magnet, and
the cartridge folder vertical motion mechanism.
The fixed optics section consists of the optical components, position detector, and LD controller.
The control circuit sections include the drive control circuit section and SCSI controller section.
Optical disk cartridge
Spindle motor
Figure 1.3Optical disk drive configuration
1.2.3Mechanical sections
(1)Optical disk cartridge load/eject
The system includes a cartridge mechanism which lowers the optical disk cartridge and mounts
(loads) it on the spindle motor automatically when the optical disk cartridge is fully inserted in
the optical disk drive’s disk slot, and a mechanism which automatically ejects the cartridge when
the Eject button on the front panel is pressed.
Control circuit section
Fixed optics sectionActuator section
(2)Spindle motor
The optical disk cartridge’s hub and the spindle motor’s shaft are connected magnetically.
Therefore, if the spindle motor’s shaft is rotating, the disk medium is rotating at the same speed.
A DC brushless motor is used for this spindle motor. It realizes high speed rotation at 4558 rpm
for MCE3064SS and 3600 rpm for MCF3064SS, and a high precision rotating system (±0.1%).
(3)Actuator section
The positioner moves (seeks) a head actuator radially across the disk surface.
The positioner is driven by a linear voice coil motor. A pulse-width modulation (PWM) is
adopted as a driving system and realizes low power consumption and high-speed access.
C156-E097-01EN1 - 7
(4)Separate optical sections
The optical head section is separated in such a way that the fixed optics section is separated from
the moving optics section to minimize seek time and positioning error. (See Subsection 1.2.4 for
the fixed optical section.) This reduces the weight of the moving parts.
The fixed optical section consists of the laser diodes, collimator lens, and optical detector.
The laser diode for recording and playback, and transmits one laser beam to the actuator section.
(5)Panel
The central part of the panel is hollowed out deeply to provide pushing finger space for inserting
the cartridge, thereby facilitating the insertion.
The panel is also simply designed by making the eject button and LED light emitting part
integral with each other.

(1)SCSI controller circuit section
The SCSI controller circuit's reliability is improved by large-scale integrated circuit technology.
The high-speed microprocessor (MPU) handles SCSI interface control and drive control such as
drive read-and-write control and single-beam control.
(2)Drive circuit section
The drive circuit section consists of the following circuits:
• Laser diode control circuit
• Signal reproduction circuit
• Servo/seek control circuit
• Rotation control circuit
• Drive miscellaneous control circuit
The DSP (digital signal processor) is used for the servo/seek control circuit to reduce the circuit
amount, therefore this circuit is a simple configuration.
The drive circuit section executes operations such as seek, erase, record, and playback while the
MPU controls the focus-tracking of the beam.
C156-E097-01EN1 - 9
1.3System Configuration
An optical disk drive connected to the system SCSI bus always operates as a target. Figure 1.5 is
a system configuration example. Through the SCSI bus, the optical disk drive executes the
input-output operation specified by the SCSI device that operates as the initiator.
Figure 1.5System configuration example
1.3.1SCSI bus configuration
A maximum of eight SCSI devices can be connected to the SCSI bus. The combination of an
SCSI device operating as an initiator and an SCSI device operating as a target is arbitrary. A
multihost system can be configured in which several host systems operate as initiators.
The disconnect or reconnect function enables input-output processing in parallel through more
than one SCSI device.
1 - 10C156-E097-01EN
1.3.2Input-output device addressing
A unique device address (SCSI ID: #n in Figure 1.5) is assigned to each SCSI device. Inputoutput devices connected to or under an SCSI device operating as a target are accessed in logical
units. A unique device address (LUN: logical unit number) is assigned to each logical unit.
An initiator specifies an SCSI ID to select an SCSI device operating as a target, then specifies an
LUN to select the input-output device connected to or under the target.
An optical disk drive is constructed with all volumes as a single logical unit. Specifiable SCSI
IDs and LUN are as follows:
• SCSI ID: #0 to #7 selectable (setting terminal or external input)
• LUN: #0 (fixed)

Notes:
1. The above data are data measured in a constant temperature chamber in which the
temperature surrounding the equipment was kept at 45°C. They are not the same as the
data obtained from measurements using the exclusive box in which the equipment is
normally used.
2.When using the box, the ambient temperature around the equipment will differ
depending on the air circulation conditions of the box, and the temperature rise inside
the cartridge will differ because of this, so please exercise caution.
3.1.5Air purity
The cleanness of the environment where this device is installed is expressed as the number of
dust particles, and it is recommended that it be used in an environment with a Class 5 million or
lower dust count. (Class 5 Million: There should be 5 million or fewer dust particles measuring
0.5 µm or larger in one cubic foot of air space. Using the gravimetric method, this corresponds
to 0.15 mg/m3.)

(1)Mounting frame structure and clearance
a) For vibration resistance and heat dissipation, this optical disk drive uses an embossed
structure as shown in Figure 3.6, as well as a frame which has a construction similar to other
frames which perform the same function.
b) As shown in Figure 3.6, the inward projection of the mounting screw from the outer surface
of the drive frame must not exceed 3 mm.
c) The clearance between the external surface of the drive frame and the user's frame structure
must be at least 1.5 mm.
d) The clearance between the top and bottom surfaces and the user's frame structure must be at
least 1.5 mm.
e) When mounting the optical disk drive, the screw tightening torque should be 0.4 to 0.45Nm
(4 to 4.6kgcm).
f) When the optical disk drive (with panel) is mounted in a locker, there should be no
deformation of the mounting fittings provided and the optical disk drive's panel should not be
deformed. If the drive is used with the panel deformed, ejection of the cartridge will be
faulty. Check if the door will close from any position whatever when the optical disk drive is
installed.

(1)SCSI cable
3.19
All SCSI devices on one bus are daisy-chained with an SCSI cable. A terminating resistor must
be mounted in the SCSI device at each end of the SCSI cable.
A terminating resistor is mounted on the drive when the drive is shipped. A terminating resistor
must be disconnected when the drive is not connected to an end of the SCSI cable. Select a
method of power supply to the terminating resistor circuit according to the setting pins on the
drive. See Section 4.3 for details.
Up to eight SCSI devices can be connected to the SCSI bus. SCSI devices include the host
adapter, the optical disk drive, and other SCSI equipment.
The connector (socket) for the SCSI cable must be an unshielded 50-contact socket with two
rows of 25 contacts on 2.54 mm (0.1 inch) centers. The connector should also be polarized or
keyed to prevent misinsertion. (See Figure 3.17.)
3 - 18C156-E097-01EN
Figure 3.17 SCSI cable connector
C156-E097-01EN3 - 19
The maximum length of the SCSI cable is as follows. If more than one SCSI device is
connected, the total length must not exceed 6 m.
A 25-pair twisted-pair cable satisfying the following requirements is recommended for the SCSI
cable:
Table 3.5SCSI cable requirements
ItemSingle-Ended type
Conductor size28 AWG or larger
Characteristic impedance
Each pair of wires must be connected to pins n and n + 1 (where n is an odd number) on the
interface connector. All cables used on the same SCSI must have the same characteristic
impedance to reduce signal reflection and to maintain transmission characteristics.
When an SCSI device is not connected to an end of the SCSI cable, connection to the SCSI
connector must be at a branching point of the cable. If an SCSI device is connected to an end of
the SCSI bus, any excess cable length after the last SCSI device must be terminated with a
resistor. (See Figure 3.18.)

A DC ground cable may or may not be installed depending on the system requirements (system
installation environment, cabinet structure, and power supply system). This cable is generally
connected to the ground of the power supply unit. Connection between more than one optical
disk drive may be in a daisy chain.
3.4.3External operator panel
Some set switch settings can be manipulated through the external operator panel interface.
Figure 3.19 shows a recommended circuit for the external operator panel. Since an external
operator panel is not provided as an option, the user must design one based on the system
requirements and the recommended circuit.
Provide switches and LEDs (required for the system) on the external
operator panel. See the recommended circuit shown in Figure 3.21.
A signal which is not set on the external operator panel connected to
CNH2 must be set using SW1. The SW1, and CNH1 corresponding to
the signal set on the external operator panel must be set to OFF
position.
For details, see Subsection 4.3.1.

Normally, with the cartridge loaded, the spindle rotation is maintained until the spindle is
instructed to stop by the START/STOP UNIT command. The spindle auto stop function
automatically stops the spindle after the command has not been issued from the host for about 30
minutes (default value). When the command is issued from the host with the spindle
automatically stopped, the optical disk derive turns the spindle again and performs processing in
the same manner as in a ready state without posting a not ready state.
The access supervision time from the host is about 33 minutes as the default. However, it can be
changed by the MODE SELECT command.
The spindle auto stop mode can also be changed by the MODE SELECT command.

4.4.2Mounting procedure
How the drive is mounted depends on the system cabinet structure. Determine the mounting
procedure in consideration of the requirements of each system. This section contains the general
mounting procedure and check items.
See Section 3.2 for details on mounting drive.
1) For a system with an external operator panel mounted, connect the external operator panel
cable before mounting the drive in the system cabinet because it is difficult to access the
connector after the drive is mounted.
2) Tighten four mounting screws to secure the drive in the system cabinet.
• The drive has ten mounting holes (both sides: 3×2, bottom: 4). Secure the drive using the
four mounting holes on both sides or the bottom.
• Use mounting screws whose lengths are 3 mm or less from the external wall of the mounting
frame of the drive when they are tightened. (See Figure 3.6)
• When mounting with screws, the screw tightening torque should be 0.4 to 0.45Nm (4 to
4.6kgcm).
• Be careful not to damage the parts on the PCA when mounting the drive.
3) After securing the drive, make sure that the drive does not touch the chassis of the system
cabinet. There must be at least 1.5 mm clearance between the drive and chassis. (See Figure
3.6)
4.5Cable Connections
Use the following cables to connect the drive to the system. See Subsection 3.4.2 for details on
the connector positions and cable requirements.
• Power supply cable
• SCSI cable
• DC ground cable (if required)
• External operator panel cable (if required)
The general procedure for cable connection and notes on connecting cables are given below. Pay
attention to the insertion direction of each cable connector.
1) Make sure that the system power is off.
2) Do not connect or disconnect any cable when the power is on.
1) Connect the DC ground cable (only if required to decrease ground noise).
2) Connect the power cables.
3) Connect the external operator panel (only if required for the system).
C156-E097-01EN4 - 13
4) Connect the SCSI cable.
5) After each cable connector is connected, secure the cable so that the cable does not touch the
drive or the parts on the PCA or obstruct the flow of cooling air in the system cabinet.
1) Be careful of the insertion directions of SCSI connectors. For a
system in which the terminating resistor power is supplied via the
SCSI cable, connecting connectors in the wrong direction may
cause the following:
The overcurrent protection fuse of the terminating resistor power
supply (SCSI device) may blow when power is turned on.
The cable may burn if overcurrent protection is not provided.
2) Be careful of cable connector positions when connecting more
than one SCSI device. The SCSI device having the terminating
resitor must be connected to the end of the cable.
3) The cables must be kept away from the rotating part of the spindle
motor.
4.6Operation Confirmation and Preparation for Use after Installation
4.6.1Confirming initial operations
This section provides the operation check procedures after the power is turned on.
(1)Initial operation when the power is turned on
• When the power is turned on, the drive starts initial self-diagnosis. The LED on the front
panel is on for 3 seconds during initial self-diagnosis.
• If an error is detected during initial self-diagnosis, the LED on the front panel blinks.
• In case of not inserted the cartridge, when the power is turned on, the eject motor
automatically turns once.
(2)Checks if errors occur at initial self-diagnosis
• Make sure that the cables are connected correctly.
• Make sure that the supply voltage is correct. (Measure the voltage at the power supply
connector of the optical drive.)
• Make sure that the settings of all terminals are correct.
4 - 14C156-E097-01EN
• If the LED on the front panel blinks continuously, an error was detected during initial self-
diagnosis. In this case, issue the REQUEST SENSE command from the initiator (host
system) to obtain sense data for error analysis.
The BUSY LED is on while the optical disk drive is executing seek,
write, or read operations. The BUSY LED is on momentarily, so it
seems as if it blinked or is off.
If the cartridge fails to be inserted, remove the cartridge and turn on
the drive power to turn the eject motor once and reinsert the
cartridge.
4.6.2SCSI connection check
When initial operation checks out normally after the power is turned on, check whether the drive
is correctly connected to the SCSI bus from the host system. Checking the SCSI connection
depends on the host system configuration. This section describes the general procedure.
(1)Procedure
Figure 4.5 shows the recommended checking procedure.
Note:
Steps a) to c) correspond to a) to c) in Figure 4.5.
a) Issue the TEST UNIT READY command and check that the drive is connected correctly to
the SCSI bus.
b) Use the WRITE BUFFER and READ BUFFER commands to check whether the SCSI bus
operates normally. Use data whose bits change to 0 or 1 at least once. (Example: A X'00' to
X'FF'increment pattern)
c) Check whether the settings are correct. Also, make sure that the controller and drive operate
normally.
C156-E097-01EN4 - 15
Figure 4.5SCSI connection check
2
4 - 16C156-E097-01EN
(2)If processing terminates abnormally:
a) If sense data has been obtained by the REQUEST SENSE command, analyze the sense data.
If the error is recoverable, retry the processing.
b) Check the following items for SCSI cable connection:
• All connectors, including other SCSI devices, are connected correctly.
• A terminating resistor is correctly mounted at both ends of the cable.
• Power is supplied to the terminating resistors correctly.
c) Check the settings of all terminals are correct. Note that the procedure of checking the SCSI
connection depends on the setting of "spindle automatic stop".
4.7Dismounting Drive
How to demount an optical disk drive (for setting terminal checking, setting change, or device
replacement) depends on the system cabinet configuration. Determine the demounting
procedure in consideration of the requirements of each system. This section describes the
general demounting procedure and notes on demounting drives.
Before demounting the optical disk drive, turn off the system power.
Do not remove screws securing the cables and drive when the power
is on.
1) Remove the power cable.
2) Remove the SCSI cable.
3) When an external operator panel is mounted, remove its cable. If it is difficult to access the
connector, remove the cable after step e).
4) Remove the DC ground cable.
5) Remove the four screws securing the drive, then remove the drive from the system cabinet.
6) When storing or transporting the drive, put the drive into an antistatic bag. (See Section 4.1.)
