Table 2.2 Specifications (2 of 2)

Item			Specifications
Optical disk media	128 MB media	230 MB media	540 MB media	640 MB media	1.3 GB media (*7)
Data buffer	2 MB
Error correction (*6)	Correctable up to 8-byte/interleave
	Bit error rate: 10-12or less

*1 The number of user tracks indicates the maximum user zone which includes the spare area and slipping area.

*2 Mathematical average of 1,000 times of random seek, which does not include command overhead or track address recognition time. Furthermore, it may depend on the quality of the media and the drive installation environment.

*3 Loading time is the time that elapses from the time an optical disk cartridge is inserted, to the time the optical disk drive is ready for processing of an access command.

*4 Unloading time is the time that elapses from the time the eject button is pressed or the eject command is issued, to the time an optical disk cartridge is ejected.

*5 The maximum SCSI data transfer rate may be limited by the initiator response time, SCSI bus transfer characteristics, or transfer distance.

*6 The bit error rate must be 10-12or less using a disk whose raw error rate is 10-4or less.

*7 The MCM3064SS and MCP3064SS do not support 1.3-gigabyte MO disks. Power save mode
