Device Overview
1-2 C141-E224
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 50 GB (formatted) on one disk using the RLL
recording method and 30 recording zone technology. The disk drive has a
formatted capacity of 100 GB (MHV2100BH), 80 GB (MHV2080BH), 60 GB
(MHV2060BH) and 40 GB (MHV2040BH) respectively.
(4) High-speed Transfer rate
The disk drive (the MHV2xxxBH Series) has an internal data rate up to 64.0
MB/s. The disk drive supports an external data rate 1.5Gbps (150MB/s)
(Serial-ATA Generation-1). And the disk drive realizes a high performance by
high-speed transfer rate combined with Native Command Queuing (NCQ).
(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 disk drive is ideal for applications since it supports the power save mode
function that works in each of the Idle, Standby, and Sleep modes and has the
Partial and Slumber interface power management functions. 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)
