General Description
1-2 C156-E227-01EN
(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 1.3 GB format as well as in the 128-MB, 230-MB, 540-MB and 640-
MB formats compatible with ISO standards.
The MCM3064AP optical disk drive supports the use of optical disks in the 128-
MB, 230-MB, 540-MB and 640-MB formats compatible with ISO standards.
(5) Direct-overwrite media support
The optical disk drive supports the use of optic modulation direct-overwrite (not
requiring an erase operation) 230-MB, 540-MB and 640-MB disks compatible
with ISO standards.
(6) 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.)
(7) Lower power consumption
The power consumption of the MCM3130AP and MCM3064AP optical disk
drive is 5.8 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 1.8 W.
(8) 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.
