Fujitsu MCM3064SS Computer Drive User Manual


 
General Description
1-2 C156-E228-02EN
(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 MCM3130SS and MCP3130SS optical disk drives support the use of
90mm(3.5-inch) optical disks in the 1.3 GB format as well as in the 128-MB, 230-
MB, 540-MB and 640-MB formats compatible with ISO standards.
The MCM3064SS and MCP3064SS optical disk drives support the use of optical
disks in the 128-MB, 230-MB, 540-MB and 640-MB formats compatible with
ISO standards.
(5) Dust resistance
With this optical disk drive, the need for a cooling fan has been eliminated owing
to its low power consumption. The optical disk drive also has a simple sealed
structure. The device is sealed with a metal plate. The drive conforms to class 5
million or less particle level. (Class 5 million: This means there are 5 million
dust particles of 0.5 mm diameter or larger per cubic foot. This is equivalent to
0.15 mg/m3.)
(6) Lower power consumption
The power consumption of the MCM3064SS, MCM3130SS, MCP3064SS and
MCP3130SS optical disk drive is 6.1 W, eliminating the need for a cooling fan.
(These power consumption values are typical values during read and write
operation.)
The minimum power consumption in the power save modes are 1.2 W.
(7) Automatic spindle stop function
If the optical disk drive is not accessed for a certain duration, it stops disk rotation
to minimize dust accumulation on the disk. This duration can be specified using
the MODE SELECT command.
