Task Alert message Page
Device damage:
Be sure to turn on the power supply before inserting your
cartridge for the first time. It releases the device from
transport protection and enables you to insert the cartridge.
The device may be damaged if you insert the cartridge
without releasing the protection. From the next time, you
don't need to turn on the power supply beforehand.
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.
• Make sure that the system power is off.
• Do not connect or disconnect any cable when the power is
on.
Device damage:
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 described above.
Damage for data medium:
Do not use this cleaning kit for the floppy disk or the optical
disk cartridge used for other optical disk drive.

CHAPTER 1 General Description
1.1 Features
1.2 Drive Configuration
This chapter describes the features and configuration of the optical disk drives.
The MCJ3230SS (hereafter, the optical disk drive) is the successor model to the
MCE3130SS. This optical disk drive, which maintains compatibility with the
MCE3130SS, offers high performance and high capacity. Supporting 2.3 GB of
storage capacity, this device delivers superior performance with a 5,455-rpm
rotational speed, and supports security functions.
The optical disk drive is high-performance, 90 mm (3.5-inch) commutative
rewritable optical disk drive which incorporates an SCSI controller.
The interface connecting the optical disk drive to the host system complies with
the SCSI-2.
The flexibility and expandability through SCSI I/F, the high performance of the
optical disk drive, and the drive's commands set enable the user to construct highreliability, high-performance disk subsystems with advanced functions and largescale storage.

General Description
1.1 Features
This section describes the following drive features:
•
Performance
•
Reliability
•
Maintainability/operability
•
Adaptability
•
Interface
1.1.1 Performance
(1) Half-height standard 90 mm (3.5-inch) size (25.4 mm height)
The SCSI controller can be connected to the system SCSI bus. The controller
meets the specifications of the standard 25.4 mm height 90 mm
(3.5-inch) fixed disk drive form factor.
(2) 2.3 GB capacity
The optical disk drive conforms to the 2.3 GB GIGAMO standard. It also
supports read and write accesses to 128 MB, 230 MB, 540 MB, 640 MB, and 1.3
GB disks.
(3) High-speed data transfer
The optical disk drive supports a disk media rotational speed of 3,637 rpm when
using 2.3 GB disks. The device supports a rotational speed of 5,455 rpm (ZCAV)
when using a 128 MB, 230 MB, 540 MB, or 640 MB disks. When using 1.3 GB
disks, the optical disk drive supports ZCAV mode with a rotational speed of 3,637
rpm, and ZCLV mode that controls the speed at three levels: 3,637/4, 138/4,801
rpm, in accordance with the position of the optical head.
In ZCLV mode, the optical disk drive speeds up by detecting continuous accessing
of inner disk tracks to prevent a reduction of inner disk rotation.
For random accesses, the optical disk drive switches to ZCAV mode that is fixed
to 3,637 rpm to prevent access performance degradation.
In the disk unit, high-speed data transfers at rates of 4.62 to 8.26 MB/s (2.3 GB)
are realized. The maximum data transfer rate on the SCSI bus is 20 MB/s in
synchronous transfer mode.
The SCSI bus high-speed data transfer capacity can be used effectively through
the optical disk unit's large capacity data buffer.

(4) 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 19 ms. (However,
this does not include command overhead or address check.)
(5) Compatible with international standards (media interchangeability)
90 mm (3.5 inch) type optical disks as well as ISO standards compatible 128 MB,
230 MB, 540 MB and 640 MB format optical disk media can be used in the optical
disk unit.
(6) Direct-overwrite medium support
The drive can use an optic modulation direct-overwrite disk that does not perform
an erase operation; 230-MB disk, 540-MB disk with the ISO standard.
(7) Dust resistance
The optical disk unit provides low-power consumption, eliminating the need for a
cooling fan. The top of the cartridge is sealed with film, and the bottom of the
optical disk unit is sealed with sheet metal, providing protection that is not
complicated.
1.1 Features
The optical disk drive needs class 5 millions or less of the dust particles.
(8) Lower power consumption
The power consumption of the optical disk drive is 6.5 W (These power
consumption values are typical values during read and write operation.) These
drives do not use a fan.
The minimum power consumption is 1.0 W (typical value) 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 failures (MTBF)
This drive features a 120,000 hour MTBF.
(2) Error recovery
For the error depending on the optical disk drive, recovery process is made by a
suitable retry. This drive features Reed-Solomon error correction (ECC) to assure
error-free operation.
C156-E224-01EN 1-3
General Description
(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.
(2) Five-year service life (no overhaul)
This drive will not require overhaul within the first five years of installation if
appropriately handled, maintained, and cleaned as recommended.
1.1.4 Adaptability
(1) Wide operating environment
An LSI circuits reduce power consumption. This drive features a wide operating
environment (5 to 45°C, general office environment). Dust particles are class 5
millions or less.
(2) Vibration resistance (shock resistance)
Rubber vibration isolators protect the drive against external shock or vibration.

1.1.5 Interface
(1) Conformance to SCSI-2
(2) Continuous block processing
(3) Data buffer
1.1 Features
This optical disk device supports the basic functions of SCSI-2.
SCSI commands enable data manipulation using logical block addresses that are
independent of the physical attributes of the optical disk device, enabling software
flexibility in terms of system expansion in the future.
Logical block addresses are used for data block addressing. Without consideration
of the physical attributes of track boundaries, the host can access data by
specifying a block number in logically continuous data space.
7,600 KB buffer is used to transfer data between the SCSI bus and disk. Since
data is stored in this buffer, the host 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 usually 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 asynchronously with the interface 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 feature is enabled or disabled by MODE SELECT command.
C156-E224-01EN 1-5
General Description
(6) 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.
(7) Device driver software
The optical disk drive requires more extended processing time than conventional
optical device drives because of higher density. Consequently, a processing time
timeout when using the OS can occur and this requires special device driver
software.
When the write cache feature is enabled, a write error is reported at
the completion status of next command. At a system so that the host
retries the command, a retry process may be failed.
