Device Overview

1.1 Features

1.1.1 Functions and performance

The fillowing features of the MHC Series and MHD Series are described.

(1) Compact

The MHC2032AT and MHC2040AT have 2 or 3 disks of 65 mm (2.5 inches) diameter, and its height is 12.5 mm (0.492 inch). The MHD2032AT and MHD2021AT have 2 disks of 65 mm (2.5 inches) diameter, and its height is 9.5

mm(0.374 inch).

(2)Large capacity

The disk drive can record up to 1,083 MB (formatted) on one disk using the (16/17) EPR4ML recording method and 12 recording zone technology. The MHC Series and MHD Series have a formatted capacity of 3.25 GB (MHC2032AT, MHD2032AT), 4.09 GB (MHC2040AT) and 2.16 GB (MHD2021AT) respectively.

(3) High-speed Transfer rate

The disk drives (the MHC Series and MHD Series) have an internal data rate up to

10.6MB/s (MHC/D2032AT). The disk drive supports an external data rate up to

33.3MB/s (U-DMA mode 2).

(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 13 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 drives (the MHC Series and MHD Series) ideal for applications where power consumption is a factor.

(2) Wide temperature range

The disk drives (the MHC Series and MHD Series) 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 drives (the MHC Series and MHD Series) is only about 30 dBA (measured at 1 m apart from the drive under the idle mode).
