(4) Average positioning time

Use of a rotary voice coil motor in the head positioning mechanism greatly increases the

positioning speed. The average positioning time is 10 ms (at read).

1.1.2 Adaptability

(1) Power save mode

The power save mode feature for idle operation, stand by and sleep modes makes the disk

drive ideal for applications where power consumption is a factor.

(2) Wide temperature range

The disk drive can be used over a wide temperature range (5°C to 55°C).

(3) Low noise and vibration

In Ready status, the noise of the disk drive is only about 3.8 bels (MPB3064AT, Typical

Sound Power per ISO7779 and ISO9296).

1.1.3 Interface

(1) Connection to interface

With the built-in ATA interface controller, the disk drive can be connected to an ATA

interface of a personal computer.

(2) 256-KB data buffer

The disk drive uses a 256-KB data buffer to transfer data between the host and the disk media.

In combination with the read-ahead cache system described in item (3) and the write cache

described in item (6), the buffer contributes to efficient I/O processing.

(3) Read-ahead cache system

After the execution of a disk read command, the disk drive automatically reads the subsequent

data block and writes it to the data buffer (read ahead operation). This cache system enables

fast data access. The next disk read command would normally cause another disk access.

But, if the read ahead data corresponds to the data requested by the next read command, the

data in the buffer can be transferred instead.

(4) Master/slave

The disk drive can be connected to ATA interface as daisy chain configuration. Drive 0 is a

master device, drive 1 is a slave device.
