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.
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.
1.1 Features (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.
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.
1.1 Features 1.1.5 Interface (1) Conformance to SCSI-2 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. (2) Continuous block processing Logical block addresses are used for data block addressing.
General Description 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. (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.
1.2 Drive Configuration 1.2 Drive Configuration 1.2.1 Drive model Figures 1.1 and 1.2 show the outer view. Figure 1.1 Outer view (with panel) Figure 1.
General Description 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.
1.2 Drive Configuration 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.
General Description 1.2.4 Control circuit section Figure 1.4 is the block diagram of the control circuit section. Figure 1.4 Control circuit section block diagram The control circuit section is divided into two parts: a controller section which deals with control between the SCSI interface and drive interface, and a drive circuit section which controls the drive. (1) Controller circuit section The controller circuit's reliability is improved by large-scale integrated circuit technology.
1.2 Drive Configuration 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.

CHAPTER 4 Host Interface 4.1 Interface Connector 4.2 Various Processes 4.3 SCSI Comands 4.4 SCSI Messages 4.5 Timing Rule This chapter describes host interface specification. 4.1 Interface Connector The nonshielded SCSI connector installed on the ODD is a 50-conductor connector consisting of two rows of 25 male pins with adjacent pins 2.54 mm (0.1 in.) apart. See Figure 4.1.
Host Interface Symbol mm Remarks C1 2.540 - C2 60.960 - C3 2.540 - C4 3.302 - C5 32.385 - C6 68.072 - C7 6.096 - C8 7.620 Maximum value Notes: 1. 2. The tolerance is ± 0.127 mm unless otherwise specified. A connector cover and strain relief are not shown in this figure. Figure 4.
4.1 Interface Connector Table 4.
Host Interface 4.2 Various Processes 4.2.1 Reset response Three types of reset responses are available. • Power-On Reset - • • The ODD performs initialization processes such as initial diagnosis and default setting. It also starts rotation of the media, if any is mounted. SCSI Reset - The ODD is reset when the RESET- signal is asserted. The ODD performs initialization of the interface controller, including such operations as writing the default values to the registers.
4.2 Various Processes 4.2.4 Cache function The ODD supports read cache and MO write cache. The read cache consists of the read-ahead cache and the LRU cache that reads write data remaining in the data buffer. The read-ahead cache enables data transfer at almost the same speed as the effective transfer speed during continuous read operation without causing delays resulting from rotation latency.
Host Interface • Data read before power-off • Data stored before media is mounted All buffer data is discarded when: • The power is turned off. • The media is ejected. • A FORMAT UNIT command is received. • The ODD is in standby mode. Buffer data may be discarded when: • A MODE SELECT command that changes the read conditions is received. 4.2.4.
4.2 Various Processes 4.2.6.1 Active mode In active mode, all circuits are enabled and the time for command processing is minimized. 4.2.6.2 Pre-idle mode In pre-idle mode, the read and write circuits are in stopped state. The ODD can receive a command from the host, but since some circuits are stopped, the command requires an additional 20 ms to access the media. The ODD automatically enters pre-idle mode if no command is issued within a specified time (0.5 s) in active mode.
Host Interface 4.2.6.6 Power mode transition The power mode transition is shown in Figure 4.3. Media insertion Active Reset Idle Standby Media ejection (1) The ODD enters idle mode because it receives no command within a specified time. (2) The ODD enters standby mode based on the standby timer. (3) The ODD enters active mode because it receives a media access command. Figure 4.
4.2 Various Processes 4.2.7 LED indications The ODD notifies the operator of a serious error by turning on or blinking an LED. Table 4.2 lists the LED indications and the corresponding operations. Table 4.
Host Interface 4.3 SCSI Commands Table 4.3 lists the SCSI commands supported by MCJ3230SS. Table 4.3 SCSI commands No.
4.3 SCSI Commands 4.3.1 TEST UNIT READY command The TEST UNIT READY command checks whether a logical unit is ready to operate. Table 4.4 TEST UNIT READY command Bit Byte 0 1 2-5 7 6 5 4 3 2 1 0 Operation Code (00h) LUN Reserved Reserved If the ODD power is on and the ODD is ready to operate, the command reports GOOD status. If the ODD is not ready or an error condition remains in the device even though the ODD is ready, the command reports CHECK CONDITION status.

Host Interface 4.4 SCSI Messages SCSI messages are used to control the SCSI bus operating sequence. This section explains how SCSI messages work. 4.4.1 Message formats There are three types of message formats. In any format, the first byte of each message is a message code (see Table 4.73). • 1-byte message: Only the message code • 2-byte message: Message with a message code from 20h to 2Fh. Each 2byte message consists of a 1-byte message code and a 1byte parameter.
4.4 SCSI Messages 4.4.3 Message functions This section explains the function of each message. The symbols in the following explanations have the following meanings: (I → T): Message that can only be sent from INIT to TARG (T → I): Message that can only be sent from TARG to INIT (I ←→ T): Message that can be sent between TARG and INIT in either direction (1) COMMAND COMPLETE message: 00h (T → I) The execution of a single command ended and valid status information was reported to INIT.
Host Interface (6) MESSAGE REJECT message: 07h (I → T) The message received most recently is invalid or unsupported. (7) NO OPERATION message: 08h (I → T) This message causes no operation. (8) MESSAGE PARITY ERROR message: 09h (I → T) This message notifies TARG that a parity error was detected in the last message, in the last byte received by the INIT. (9) BUS DEVICE RESET message: 0Ch (I → T) This message instructs the clearing of all I/O operations (commands) being executed or stacked in TARG.

5.1 Operating Optical Disk Drive 5.1.2 Note To maintain the performance and reliability of the drive, keep the following point in mind: • When the drive is in the busy state, do not eject the optical disk cartridge. Particularly, do not manually eject the cartridge by force. • Be careful sufficiently not to insert the different drive (etc. floppy disk) or substance, so it is cause of the accident. 5.1.3 Inserting cartridge Insert the cartridge as explained below. (See figure 5.
Operation and Cleaning 4) Push the cartridge into the slot until it completes moving below (a little further in than the operator panel). The cartridge remains inserted in the drive. The BUSY LED indicator lamp lights when the drive power is turned on. The cartridge remains inserted in the drive. Turning on the drive power starts loading. (The LED indicator lamp should light.
5.1 Operating Optical Disk Drive 5.1.4 Ejecting (removing) cartridge Remove the cartridge as explained below. (1) When the drive power is on: The cartridge can be removed by pressing the eject button. (See figure 5.3) Notes: 1) If the SCSI command prevents ejection, the cartridge cannot be removed. 2) Even if the drive set-up conditions are met, note that the cartridge can drop from the drive after ejection depending on the ambient environment and the cartridge's condition.
Operation and Cleaning 5.2 Cleaning Drive When a dust or smoke of cigarette is stained to the lens actuator, a performance of whole drive may be down. Clean the lens actuator periodically using following head cleaner. Note: Cleaning period differs depending on the installation condition. Usually, cleaning period is once a three months.

Operation and Cleaning 5.3.2 Write protect tab Moving the write protect table determines whether to enable or disable writing of the optical disk cartridge. Use a fingernail to move the write protect tab (it must be completely moved to the end because there is play in the middle). Figure 5.5 shows the write protect tab location on the optical disk cartridge and the moving state of the write protect tab (see "write enabled" and write disabled" entered on the label).
5.3 Optical Disk Cartridge Operation 5.3.3 How to affix an index label on the MO cartridge (See figure 5.6) (1) Note the following when affixing an index label: • Be careful not to let the label become misaligned. • Be sure to prevent the formation of air bubbles or peeling. (2) How to affix an index label Follow the procedure below when affixing an index label. (See Figure 5.x.) 1) Clean the surface of the MO cartridge before affixing the index label.
Operation and Cleaning (2) When storing the cartridge: • Do not place a heavy objects on the cartridge. • Do not store the cartridge where exposed to direct sunlight or where the temperature changes sharply, the temperature is high, or the humidity is high. • Do not store the cartridge in a dusty or smoky place. (3) When transporting the cartridge: 5-10 • Put the cartridge in a nylon bag to protect it from moisture.
5.4 Cleaning Optical Disk Cartridge 5.4 Cleaning Optical Disk Cartridge Dust or cigarette smoke particulates on the disk surface lowers the performance of the cartridge. Regularly clean the disk. The cleaning frequency depends on the drive installation environment. Determine how often the drive should be cleaned in consideration of the environment. A standard of he cleaning period is every 300 hours usage or once a 2 to 3 months. 5.4.1 Cleaning tool Use the cleaning kit to clean the disk cartridge.
Operation and Cleaning Damage for disk medium: 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. (2) Notes on usage and storage of cleaning kit • When storaging the cleaning solution, tighten the cap. • As the magnet is used at revolving knob of the setting case, do not place the floppy disk near the revolving knob. • Do not use or storage where exposed to direct sun light or near the inflammables.
