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
9.5mm (0.374 inch).
(2)Environmental Protection
The disk drive comply with the RoHS (Restriction of the use of certain Hazardous Substances in electrical and electronic equipment) directive issued by European Union (EU).
(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 (MHW2120BS), 100 GB (MHW2100BS), 80 GB (MHW2080BS), 60 GB (MHW2060BS) and 40 GB (MHW2040BS) respectively.
(4) High-speed Transfer rate
The disk drive (the MHW2xxxBS Series) has an internal data rate up to
61.3MB/s. The disk drive supports an external data rate 1.5Gbps (150MB/s)
(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) Temperature range
The disk drive can be used temperature range (5 °C to 60°C at DE surface). (For details of the reliability for each temperature range, refer to the Section 1.7, "Reliability.")
