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 hazardous situation likely to result in
serious personal injury if the user does not perform the
procedure correctly.
This indicates a hazardous situation could result in serious
personal injury if the user does not perform the procedure
correctly.
This indicates a hazardous 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 does not perform the product correctly.
This indicates information that could help the user use the
product more efficiently.
Attention
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)
While the write cache feature is enabled, a write error is reported in the
completion status of another command that is subsequent to the concerned
write command. Note that, if the host performs only retry of an errorreporting command, data in the block in which the error has occurred is not
correctly written.
The main alert messages in the text are also listed in the “Important Alert Items.”
Please forward any comments you may have regarding this manual.
To make this manual easier for users to understand, opinions from readers are needed.
Please write your opinions or requests on the Comment at the back of this manual and

Installation
Data loss: Data is not guaranteed if a power failure occurs or the I/F
cable is pulled out while:
• Data is being written to a data block
• A disk is being initialized (formatted)
• Defect processing is in progress
Data is not guaranteed either if the drive is moved with the optical disk
cartridge inserted or the drive is exposed to excessive shock or
vibration.
Data loss: 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 th e drive. Do not
touch the PCA except when setting the switches.

3-23
4-1
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.
5) Do not forcibly push up the end of the header pin of the printed
circuit board unit when handling or setting the drive.

Installation
Before moving the drive, remove the optical disk cartridge. If the drive is
moved with the optical disk cartridge loaded in it, the head may move
back and forth in the drive to damage the head or disk and reading the
data may fail
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 resistor
must be connected to the end of the cable.
3) The cables must be kept away from the rotating part of the spindle
motor.

Cleaning cartridge
Maintenance and Repair
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.
Device Damage: Be sure to use the dedicated head cleaner shown
above.
Disk damage: To clean a disk, use the cleaning solution and cleaning
cloth specified in Table 5.2.
Disk damage: Do not use this cleaning kit on a floppy disk or an
optical disk cartridge to be used on other optical disk drives.
Disk damage: Clean a cartridge in a dust-free environment.
Fujitsu recommends wearing disposable gloves during cleaning so that
no fingerprints are left on a disk.
Disk damage: Do not press hard or apply excessive shock to an optical
disk cartridge case while setting it in the settin g case.
Eye inflammation: If the cleaning so lution gets into your eyes,
immediately wash the solution away with water.
Data loss: For a repair request, you normally do not need to include
any optical disk cartridge with an optical disk drive. However, you do
need to include a cartridge if errors keep occurring with a specific
cartridge. In such a case, be sure to save data stored in the cartridge
before sending it in. Fujitsu shall bear no responsibility for any data lost
during service or repair.

CHAPTER 1 General Description
1.1 Features
1.2 Configuration of Optical Disk Drive
This chapter describes the features and configuration of the MCM3064SS,
MCM3130SS, MCP3064SS and MCP3130SS optical disk drives.
As successors to the MCE3064SS and MCE3130SS optical disk drives, the
MCM3064SS, MCM3130SS, MCP3064SS and MCP3130SS optical disk drives
(hereafter called the optical disk drives) achieve high-speed operation while
maintaining compatibility with the MCE3064SS and MCE3130SS.
The flexibility and expandability realized through SCSI interfaces as well as the
high performance and command sets of the optical disk drives allow the user to
construct disk subsystems featuring advanced functions, high performance, largescale storage and high reliability.
1.1 Features
This section describes the features of the optical disk drives in terms of
performance, reliability, maintainability/operability, adaptability, and interface.
1.1.1 Performance and Functions
(1) Half-height standard 90mm(3.5-inch) size (25.4 mm height)
The optical disk drives can be directly connected to the system SCSI bus. The
drive employs the same form factor as that for the 90mm(3.5-inch) 25.4-mm
height hard disk drive.
(2) High-speed data transfer
The MCM3130SS and MCP3130SS rotate disks at 3,637 revolutions per minute
when 1.3 GB disks are used. When other media are used, the speed is 5,455
revolutions per minute.
The MCM3064SS and MCP3064SS rotate disks at 5,455 revolutions per minute.
In the disk drive, the MCM3130SS and MCP3130SS realize high-speed data
transfers at rates of 3.92 to 6.70 MB/s (1.3 GB) and the MCM3064SS and
MCP3064SS realize at rates of 3.52 to 5.87 MB/s (640 MB). The maximum
synchronous data transfer speed of the SCSI bus is 20 MB/s.
The data transfer capacity can be used effectively through a large capacity data
buffer of the optical disk drive.

General Description
(3) High-speed mean seek time
This drive features a linear voice coil motor for high-speed head positioning.
The average seek time per 1,000 random seeks is 23 ms. (However, this does not
include command overhead or address check.)
(4) Compatibility with international standards (media interchangeability)
The MCM3130SS and MCP3130SS optical disk drives support the use of
90mm(3.5-inch) optical disks in the 1.3 GB format as well as in the 128-MB, 230MB, 540-MB and 640-MB formats compatible with ISO standards.
The MCM3064SS and MCP3064SS optical disk drives support the use of optical
disks in the 128-MB, 230-MB, 540-MB and 640-MB formats compatible with
ISO standards.
(5) Dust resistance
With this optical disk drive, the need for a cooling fan has been eliminated owing
to its low power consumption. The optical disk drive also has a simple sealed
structure. The device is sealed with a metal plate. The drive conforms to class 5
million or less particle level. (Class 5 million: This means there are 5 million
dust particles of 0.5 mm diameter or larger per cubic foot. This is equivalent to
0.15 mg/m3.)
(6) Lower power consumption
The power consumption of the MCM3064SS, MCM3130SS, MCP3064SS and
MCP3130SS optical disk drive is 6.1 W, eliminating the need for a cooling fan.
(These power consumption values are typical values during read and write
operation.)
The minimum power consumption in the power save modes are 1.2 W.
(7) Automatic spindle stop function
If the optical disk drive is not accessed for a certain duration, it stops disk rotation
to minimize dust accumulation on the disk. This duration can be specified using
the MODE SELECT command.

1.1 Features
1.1.2 Reliability
(1) Mean time between failures (MTBF)
The mean time between failures (MTBF) for this optical disk drive is 120,000
hours or more.
(2) Enhanced error recovery
If an error occurs on the optical disk drive, the system executes appropriate retry
processing to recover from it. This drive features enhanced Reed-Solomon error
correction code (ECC) to assure error-free operation.
(3) Automatic allocation of alternate data blocks
This drive features a function which automatically allocates alternate data blocks
in cases where defective data blocks are detected while data is being written to an
optical disk.
1.1.3 Maintainability/operability
(1) Diagnostics function
This drive has a diagnostics function for checking optical disk drive operations.
The diagnostics function facilitates test and restoration.
(2) Five-year service life (no overhaul)
This drive will not require overhaul within the first five years of installation if
appropriately maintained (both disks and optical parts cleaned using cleaning
tools) and handled as recommended.
1.1.4 Adaptability
(1) Wide-ranging operating environments
This drive, requiring low power consumption because of LSIs adopted, can be
used in wide-ranging environments (5 to 45°C for drive's ambient environment
and a general office environment). The ambient cleanliness must be class 5
million or less particle level.
(2) Low noise
This drive operates quietly at 30 dB or less (A-character) during seek operations
and will not degrade the office environment (except when an optical disk is
ejected).

General Description
(3) Safety standards
The optical disk drive is certified under the following standards:
• UL1950 (U.S. safety standard)
• CDRH (U.S. laser standard) (Class 1)
• CSA C22.2 No. 950 (Canada safety standard)
• EN60950 (European safety standard)
• EN60825-1 (European laser standard) (Class 1)
(4) Radio wave standards
This optical disk device, while installed, is certified under the following
standards:
EN55022 class B, EN55024 (European EMC standard)
AS/NZS3548 class B (Australian EMC standard)
CNS13438 class B (Taiwanese EMC standard)
1.1.5 Interface
(1) Conformation to SCSI-2
The optical disk drives conform to the basic specifications of SCSI-2.
SCSI commands specify data with logical block addresses, thus allowing data to
be manipulated independent of the physical characteristics of the optical disk
derives. This facilitates easy development of software whose functions can be
flexibly expanded in the future.
(2) Continuous block processing
Logical block addresses are used for data block addressing. Irrespective of the
physical attributes of track boundaries, you can have the initiator access data by
specifying a block number in logically continuous data space.
(3) High-capacity data buffer
This drive has a 2 MB data buffer. This data buffer is used to transfer data
between the SCSI bus and a disk. Since data is stored in this buffer, the host can
execute input-output processing effectively by using the data transfer capability of
the SCSI bus irrespective of the effective data transfer rate of the optical disk
drive.
1-4 C156-E228-02EN
1.1 Features
(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 drive can transfer data from the buffer without
accessing the disk again.
(5) Write cache feature
When the host system issues the write command to the optical disk drive, this
drive would report completion of the command after completion of the write and
verify operations if the write cache feature were not used. If the write cache
feature is used, this drive reports completion of the command when data transfer
to buffer is completed, without waiting for completion of the write and verify
operations. This drive performs the write and verify operations asynchronously
with the interface operation. Therefore, enabling the write cache reduces the
apparent write command processing time recognized by the host system and
improves the I/O performance of the host system.
Enable or disable the write cache feature using the MODE SELECT command.
While the write cache feature is enabled, a write error is reported in
the completion status of another command that is subsequent to the
concerned write command. Note that, if the host performs only
retry of an error-reporting command, data in the block in which the
error has occurred is not correctly written.
(6) Defective block slipping
While initializing a disk, the optical disk drive slips defective data blocks to
reallocate logical data blocks so they are physically continuous. This enables
high-speed continuous data block processing without rotational delay due to
defective data blocks.

1.2 Configuration of Optical Disk Drive
1.2.2 Configuration
Figure 1.3 shows the configuration of the optical disk drive.
The optical disk drive consists of a mechanical section, a fixed optics section, a
control circuit section, and an actuator.
The mechanical section includes the spindle motor, actuator section, bias magnet,
and cartridge holder vertical motion mechanism.
The fixed optics section consists of the optical components, position detector, and
LD controller.
The control circuit section includes the drive control circuit section and I/F circuit
section.

1.2.3 Mechanical section
(1) Loading and ejecting an optical disk cartridge
Control circuit section
Fixed optics section
The optical disk drive includes a cartridge load mechanism and an auto eject
mechanism. If an optical disk cartridge is manually inserted in the drive's slot as
far as it will go, the cartridge load mechanism automatically lowers the cartridge
and mounts it on the spindle motor. If the Eject button on the front panel is
pressed, the auto eject mechanism automatically ejects the cartridge.
(2) Spindle motor
An optical disk cartridge hub and the spindle motor shaft are magnetically
combined. Therefore, a disk rotates as fast as the spindle motor shaft rotates. The
spindle motor, a DC brushless motor, provides high-speed rotation at 5,455 rpm
and 3,637 rpm and high-accuracy rotation at ± 0.1%.
C156-E228-02EN 1-7
General Description
(3) Actuator section
The actuator section consists of a focus actuator and a tracking actuator. The
former focuses a laser beam on the surface of an optical disk while the latter
moves the beam spot along the radius, on the surface of an optical disk (seek
operation).
The actuator section is directly driven by a linear voice coil motor. The tracking
actuator is based on the pulse-width modulation (PWM) system and realizes low
power consumption and high-speed access.
(4) Separate optical sections
The optical head section has a split structure in which the fixed optics section is
separated from the moving optics section to minimize seek time and positioning
error. This reduces the weight of the moving parts.
The fixed optics section consists of the laser diodes, collimator lens, separation
prism, condensing lens, and the optical detector.
A laser diode for recording and playback transmits one laser beam to the actuator
section.
(5) Panel
The central part of the panel is hollowed out to provide enough space to enable
the cartridge to be inserted by pushing it with a finger, thereby facilitating
insertion.
The panel is also simply designed using an eject button that also serves as LED
light emitting part.
