Device Overview
1-2 C141-E218
1.1 Features 1.1.1 Functions and performance
The following features of the disk drive are described.
(1) Compact
The disk drive has up to 2 disks of 65 mm (2.5 inches) diameter, and its height is
9.5 mm (0.374 inch).
(2) Green product
The disk drive is lead (Pb)-free products and the European Parliament and
Council Directive on the Restriction of the use of certain Hazardous Substances in
electrical and electronic equipment (the RoHS Directive) compliant.
(3) Large capacity
The disk drive can record up to 60 GB (formatted) on one disk using the RLL
recording method and 30 recording zone technology. The disk drive has a
formatted capacity of 120 GB (MHV2120AT), 100 GB (MHV2100AT), 80 GB
(MHV2080AT), 60 GB (MHV2060AT) and 40 GB (MHV2040AT).
(4) High-speed Transfer rate
The disk drive (the MHV Series) has an internal data rate up to 41.3 MB/s. The
disk drive supports an external data rate up to 100 MB/s (U-DMA mode 5).
(5) 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, Standby and Sleep modes and
automatically power down by APM function makes the disk drive ideal for
mobile use 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 (while the device is waiting for any commands), the Sound Power
level of the disk drives in idle mode is 1.5B [MHV2040AT]/2.3B [MHV2060AT,
