1.1 Features
1.1.1 Functions and performance
The following features of the MHS Series are described.
(1) Compact
The MHS Series has 1 disk or 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 30 GB (formatted) on one disk using the 48/50
RLL recording method and 30 recording zone technology. The MHS Series has a
formatted capacity of 60 GB (MHS2060AT), 40 GB (MHS2040AT), 30 GB
(MHS2030AT) and 20 GB (MHS2020AT) respectively.
(3) High-speed Transfer rate
The disk drives (the MHS Series) have an internal data rate up to 38.1 MB/s. The
disk drive supports an external data rate up to 100 MB/s (U-DMA mode 5).
(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 12 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 MHS Series) ideal for applications where power consumption
is a factor.
(2) Wide temperature range
The disk drives (the MHS 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 MHS Series) is only 24 dBA
(measured at 0.3 m apart from the drive under the idle mode).
(4) High resistance against shock
The Load/Unload mechanism is highly resistant against non-operation shock up
to 8820 m/s
2
(900G).
