Conventions for Alert Messages
This manual uses the following conventions to show the alert messages. An alert message consists of an
alert signal and alert statements. The alert signal consists of an alert symbol and a signal word or just a
signal word.
The following are the alert signals and their meanings:
This indicates a hazarous situation likely to result in serious personal
injury if the user does not perform the procedure correctly.
This indicates a hazarous situation could result in personal injury if the
user does not perform the porocedure correctly.
This indicates a hazarous situation could result in minor or moderate
personal injury if the user does not perform the procedure correctly. This
alert signal also indicates that damages to the product or other property,
may occur if the user oes not perform the procedure correctly.
This indicates information that could help the user use the product more
efficiently.
In the text, the alert signal is centered, followed below by the indented message. A wider line space
precedes and follows the alert message to show where the alert message begins and ends. The following
is an example:
(Example)
Before moving the drive, remove the optical disk cartridge to avoid
head or disk damage
The main alert messages in the text are also listed in the “Important Alert Items.”

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
frame, avoid putting force.

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
4-5
4-13
4-14
3) The cables must be kept away from the rotating part of the
spindle motor
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.
Cleaning cartridge Use the cleaning solution and cleaning cloth specified in Table
5.2. If other than the specified items is used, disk media surface
may be damaged.
Do not use this cleaning kit for the floppy disk or the optical disk
cartridge used for other optical disk drive.
Clean the cartridge at clean place. Put a disposable groves at
cleaning so that the figureprint does not put on the disk media
(recommendation).
At setting the cartridge to the setting case, do not apply the heavy
shock and push hardly.
In case of contact with eyes, immediately flush eyes with water.
Maintenance and Repair Data loss
In case of regular repair, the optical disk cartridge should not be
attached except where the cartridge causes the error. And before
having the drive repaired, save the data in the cartiridge. Fujitsu
is not responsible for data last during maintenance or repair.

CHAPTER 1 GENERAL DESCRIPTION
1.1 Features
1.2 Drive Configuration
1.3 System 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.
1.1 Features
This section describes the following drive features:
• Performance
• Reliability
• Maintainability/operability
• Adaptability
• Interface
C156-E097-01EN 1 - 1
1.1.1 Performance
(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.

(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.
1.1.2 Reliability
(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.
1.1.3 Maintainability/operability
(1) Diagnostic function
This drive has a diagnostic function to check optical disk drive operations. The diagnostic
function facilitates test and restoration.
C156-E097-01EN 1 - 3
1.1.4 Adaptability
(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)
1.1.5 Interface
(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 - 4 C156-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.

1.2.2 Configuration
Figure 1.3 shows the drive configuration.
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.

1.2.3 Mechanical 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-E097-01EN 1 - 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.

1.3 System 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 1.5 System configuration example
1.3.1 SCSI 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 - 10 C156-E097-01EN
1.3.2 Input-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)
