CHAPTER 1 General Description 1.1 Features 1.2 Configuration of Optical Disk Drive This chapter describes the features and configuration of the MCM3064AP and MCM3130AP optical disk drives. As successors to the MCE3064AP and MCE3130AP optical disk drives, the MCM3064AP and MCM3130AP optical disk drives (hereafter called the optical disk drives) achieve high-speed operation while maintaining compatibility with the MCE3064AP and MCE3130AP.
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 MCM3130AP optical disk drive supports the use of 90mm(3.5-inch) optical disks in the 1.
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.
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.
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.
General Description 1.2 Configuration of Optical Disk Drive 1.2.1 Appearance Figures 1.1 and 1.2 show the optical disk drive. Figure 1.1 The optical disk drive (with panel) Figure 1.
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.
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.

4.4 Various Processes 4.4 Various Processes 4.4.1 Reset response There are four types of resets. • Power-on reset − • Hardware reset − • The ODD performs initialization such as initial diagnostics and default setting. If any media is mounted, it also spins up media. The ODD is reset when the RESET- signal is asserted. The ODD initializes the interface controller by setting default values. ATA software reset − The ODD is reset when the SRST bit of the Device Control register is set.
Host Interface 4.4.2 Defect sector management Sector mapping is executed based on the ISO/IEC 10090 standard for 128 MB media, the ISO/IEC 13963 standard for 230 MB media, the ISO/IEC 15041 standard for 540 and 640 MB media, and GIGAMO 1.3 GB 90 mm Magnetooptical Disk System-System Description for 1.3 GB media. Basically, possibly defective sector management is not required for the host. Defective sectors cannot be deleted from the host, except for certifying recordable areas.
4.4 Various Processes 4.4.4 Data error detection criteria Table 4.15 lists the ID and data error detection criteria for data access commands and for error processing. Table 4.15 ID and data error detection criteria and error processing details Command FORMAT UNIT ID read error Data error Error processing details 128/230 MB media: 3 read errors in 3 sectors 4 or more bytes per interleave Defective sectors are registered in PDL (Primary Defect List).
Host Interface 4.4.5 Cache function The ODD supports the 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 allows for data transfer at a near effective transfer speed during continuous read operation without causing any delay owing to rotation latency. LRU allows for data transfer with no mechanical operation if write and read operations are executed frequently on the same sector.
4.4 Various Processes When the cache is enabled, the buffer contains data transferred from the host with a write command. If a read command is issued to the sector address at this time, the ODD directly transfers data to the high-level equipment from the data buffer without reading it from media. If the cache is hit with a read command, the ODD makes the data in the hit segment being kept in the highest priority. The data listed below cannot be stored in the read cache.
Host Interface • When software is reset or the DEVICE RESET command is received Under the condition given below, the command end response to host and data transfer processing may wait until writing to media is completed: • When all data buffer segments are in use, and a command requiring a new segment is received Under the conditions given below, write data in the buffer may not be written properly on media: • Power-off • Hardware reset • Forced media ejection (mechanical ejection) 4.4.
4.4 Various Processes 4.4.7.1 Power mode The ODD supports power modes shown below. The ODD uses a power mode equivalent to standby mode, except that the DRDY bit is 0 while media is not mounted. • Active mode • Pre-idle mode • Idle mode • Standby mode • Sleep mode 4.4.7.2 Active mode In active mode, all circuits are enabled. The ODD requires the shortest time to start processing a command. 4.4.7.3 Pre-idle mode In pre-idle mode, the read/write circuits stop.
Host Interface 4.4.7.5 Standby mode In standby mode, the spindle motor stops. The ODD can receive a command from the host, but since the spindle motor stops, the recovery to access media takes 5 s (standard). The ODD automatically enters standby mode from active mode if no command is issued within a specified time when the standby timer is enabled. When it receives a command, the ODD automatically returns active mode.
4.4 Various Processes 4.4.7.8 Power mode transition The power mode transits as shown in Figure 4.1. Media is inserted. (1) Reset Active (4) (4) (3) (5) (2) (3) Standby Media is ejected. (5) (5) Sleep (1) The ODD enters idle mode because it receives the Idle Immediate command or because it receives no commands within a specified time. (2) The ODD enters idle mode with the Idle Immediate command. (3) The ODD enters standby mode with the Standby Immediate command and standby timer.
Host Interface 4.4.8 LED Indications The ODD notifies the operator of a serious error by turning on or blinking the LED lamp. Table 4.16 lists indication modes and operation. Table 4.

CHAPTER 5 Operation and Cleaning 5.1 Operation of Optical Disk Drive 5.2 Cleaning of Optical Disk Drive 5.3 Operation of Optical Disk Cartridge 5.4 Cleaning of Optical Disk Cartridge This chapter describes how to operate and clean the optical disk drive and an optical disk cartridge. 5.1 Operation of Optical Disk Drive The optical disk drive has automatic load and eject functions. All of the operator must do about the drive is to insert an optical disk cartridge and push the eject button.
Operation and Cleaning 1) Disk insertion slot Insert and eject an optical disk cartridge into and out of this slot. 2) Eject button & BUSY LED (indicator lamp) On this optical disk drive, the eject button serves also as the BUSY LED (indicator lamp). Eject an optical disk cartridge by pressing this button, which also goes on in green during seeking and during erasing, writing or reading of data. When ejection is disabled by an ATAPI command, an optical disk cartridge cannot be taken out.
5.1 Operation of Optical Disk Drive 3. If the BUSY LED indicator lamp does not go on after a cartridge is inserted, press the eject/BUSY LED button once to eject the cartridge and insert it again. 4. Do not forcibly insert a cartridge if you have any difficulty inserting it. If you do, the drive may be damaged. In such a case, be sure to remove the cartridge once and check the insertion orientation and the face and back of the cartridge before inserting it again.
Operation and Cleaning If you insert an optical disk cartridge with the printed shutter facing upward by pressing on the rear of cartridge at the left edge, you may hear an audible click but the drive may not become READY. In such a case, press the cartridge further by pressing on the back of the cartridge from the center (somewhere near the notched section of the panel front) until the LED indication lamp goes on. If this happens, the cartridge has been normally inserted. 5.1.
5.2 Cleaning of Optical Disk Drive Press the eject switch Figure 5.3 Removing an optical disk cartridge 5.2 Cleaning of Optical Disk Drive The drive performance may deteriorate if dust, particle or cigarette smoke deposits accumulate on the lens actuator of the drive. Clean the lens actuator periodically using following head cleaner (*1). *1 How often the lens actuator should be cleaned varies depending on the environment in which the optical disk drive has been installed.
Operation and Cleaning Device Damage: Be sure to use the dedicated head cleaner shown above. Check the state of the cleaning brush by opening the shutter of the head cleaner. If the tips of the brush bristles are spread out, the lens cannot be completely cleaned. In such a case, use a new head cleaner. 5.3 Operation of Optical Disk Cartridge 5.3.1 Appearance Figure 5.4 shows the appearance of an optical disk cartridge.
5.3 Operation of Optical Disk Cartridge (a) Shutter closed (2) Shutter (1) Cartridge case (3) Write protect tab (b) Shutter open (4) Disk (5) Hub Figure 5.
Operation and Cleaning 5.3.2 Write protect tab Move the write protect tab to enable or disable writing to an optical disk cartridge. Use a fingernail or something similar to move the write protect tab (it must be completely moved to one end because there is some play in the middle). Figure 5.5 shows where the write protect tab is located on a optical disk cartridge and how the write protect tab should be moved (see the Write Enabled and Write Disabled indications printed on the label).
5.3 Operation of Optical Disk Cartridge 5.3.3 Precautions To maintain the performance and reliability of an optical disk cartridge, keep the following points in mind when using, storing, or transporting an optical disk cartridge: (1) Using a cartridge • Do not use a cartridge in an environment where it is exposed to direct sunlight or sharp temperature changes, or high temperature or humidity. • Do not press hard, drop, or otherwise apply excessive shock or vibration to a cartridge case or shutter.
Operation and Cleaning 5.4 Cleaning the Optical Disk Cartridge You must periodically clean an optical disk cartridge because the accumulation of dust, particle, or cigarette smoke deposits on the disk lowers the performance of the cartridge. How often the cartridge should be cleaned varies depending on the environment in which the optical disk drive has been installed. Usually, clean the cartridge once every 300 hours of operation or once in two to three months. 5.4.
5.4 Cleaning the Optical Disk Cartridge (2) Precautions on use and storage of cleaning kit Keep the following in mind when using or storing the cleaning kit: • Tighten the cap after using the cleaning solution. • Do not insert a floppy disk or stack floppy disks in the setting case because a magnet is used at the disk revolving knob of the setting case. • Do not use or store the cleaning kit in an environment where it is exposed to direct sunlight or near a flame.
Operation and Cleaning Cartridge Shutter Spindle Optical disk Shutter stopper Setting case lid Setting case Figure 5.7 Setting an optical disk cartridge into the setting case Disk damage: Do not press hard or apply excessive shock to an optical disk cartridge case while setting it in the setting case. 3) Place the setting case cover over the cartridge while inserting the disk revolving knob pin into the center hub of the cartridge (see Figure 5.8).
5.4 Cleaning the Optical Disk Cartridge Eye inflammation: If the cleaning solution gets into your eyes, immediately wash the solution away with water. 6) Gently wipe the disk surface, going from the center to the edge of the disk. 7) After wiping, turn the disk-revolving knob and then wipe the next section in the same manner (see Figure 5.9).
Operation and Cleaning Cleaning cloth Figure 5.9 Cleaning of disk surface 8) Wipe off any excess cleaning solution remaining on the disk surface, using a new portion of the cleaning cloth (where no cleaning solution is absorbed).
CHAPTER 6 Diagnostics and Maintenance 6.1 Diagnostics 6.2 Maintenance Information This chapter provides diagnostics and maintenance information. 6.1 Diagnostics Table 6.1 lists test items during diagnostics. The optical disk drive has a self-diagnostics function. This function can check the normality of basic operations of the drive. To check the generation operations including the operations of the interface with the host system, provide a test program that can run in the host system (see Section 6.1.
Diagnostics and Maintenance 6.1.2 Diagnostic command The host system issues the EXECUTIVE DEVICE DIAGNOSTIC command to cause the ODD to execute self-diagnostics. See the description on the EXECUTIVE DEVICE DIAGNOSTIC command for more information. 6.1.3 Test program To check the operations of the interface with the host system and the general operations in an environment that simulates an actual operation status, provide a test program that can run in the host system.
6.2 Maintenance Information b) Failure status c) − Date of failure − System configuration − Environment conditions (temperature, humidity, supply voltage, etc.) Failure history d) Failure description − Description of failure − Issued commands and specified parameters − Sense data − Other error analysis information Data loss: For a repair request, you normally do not need to include any optical disk cartridge with an optical disk drive.
Diagnostics and Maintenance (1) Indication of revision number at shipment The revision number indicated on the drive at the time of shipment is indicated by marking (crossing out) the numbers up to the pertinent number using double lines (=) in the line of the pertinent alphabetic character (see Figure 6.2).
