Device Overview
1.1 Features
1.1.1 Functions and performance
The following features of the disk drive is described.
(1) Compact
The disk drive 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 40 GB (formatted) on one disk using the RLL recording method and 30 recording zone technology. The disk drive has a formatted capacity of 80 GB (MHT2080BH), 60 GB (MHT2060BH), 40 GB (MHT2040BH) respectively.
(3) High-speed Transfer rate
The disk drive (the MHT Series) has an internal data rate up to 53.9 MB/s.
The disk drive supports an external data rate up to 1.5Gbps
(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 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.
(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 2.2 Bels [MHT2040BH]/2.8 Bels [MHT2080BH, MHT2060BH]. The Sound Pressure level is 25.0 dB [MHT2040BH]/34.0 dB [MHT2080BH, MHT2060BH] as measured 0.3 m from the drive in Idle mode.
(4) High resistance against shock
The Load/Unload mechanism is highly resistant against
