1.2Configuration 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, large- scale 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.
