Device Overview
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) Environmental Protection
The disk drive complies with the Restriction of the use of certain Hazardous
Substances in electrical and electronic equipment (RoHS) directive issued by
European Union (EU).
(3) Large capacity
The disk drive can record up to 160 GB (formatted) on one disk using the RLL
recording method and 30 recording zone technology. The disk drive has a
formatted capacity of 320 GB (MHZ2320BJ), 250 GB (MHZ2250BJ),
200 GB (MHZ2200BJ), 160 GB (MHZ2160BJ), 120 GB (MHZ2120BJ), and
80 GB (MHZ2080BJ) respectively.
(4) High-speed Transfer rate
The disk drive (the MHZ2xxxBJ Series) has an internal data rate up to
118.4 MB/s. The disk drive supports an external data rate 3.0 Gbps (300 MB/s)
(Serial-ATA Generation-2) or 1.5 Gbps (150 MB/s) (Serial-ATA Generation-1) by
each model. 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 10.5 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.
