1.1 Features

(4) High-speed mean seek time

This drive features a linear voice-coil motor for high-speed head positioning. The average seek time is the average of 1,000 random seeks and is 19 ms. (However, this does not include command overhead or address check.)

(5) Compatible with international standards (media interchangeability)

90 mm (3.5 inch) type optical disks as well as ISO standards compatible 128 MB, 230 MB, 540 MB and 640 MB format optical disk media can be used in the optical disk unit.

(6) Direct-overwrite medium support

The drive can use an optic modulation direct-overwrite disk that does not perform an erase operation; 230-MB disk, 540-MB disk with the ISO standard.

(7) Dust resistance

The optical disk unit provides low-power consumption, eliminating the need for a cooling fan. The top of the cartridge is sealed with film, and the bottom of the optical disk unit is sealed with sheet metal, providing protection that is not complicated.

The optical disk drive needs class 5 millions or less of the dust particles.

(8) Lower power consumption

The power consumption of the optical disk drive is 6.5 W (These power consumption values are typical values during read and write operation.) These drives do not use a fan.

The minimum power consumption is 1.0 W (typical value) during power save.

(9) Automatic spindle stop function

If access is not made within a certain time, this function stops disk rotation to minimize dust accumulation on the disk. This function can be set that time by the MODE SELECT command.

1.1.2Reliability

(1)Mean time between failures (MTBF)

This drive features a 120,000 hour MTBF.

(2) Error recovery

For the error depending on the optical disk drive, recovery process is made by a suitable retry. This drive features Reed-Solomon error correction (ECC) to assure error-free operation.
