CHAPTER 1 General Description 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.
