1.1 Features
1.1.1 Functions and performance
The fillowing features of the MHC Series and MHD Series are described.
(1) Compact
The MHC2032AT and MHC2040AT have 2 or 3 disks of 65 mm (2.5 inches)
diameter, and its height is 12.5 mm (0.492 inch). The MHD2032AT and
MHD2021AT have 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 1,083 MB (formatted) on one disk using the
(16/17) EPR4ML recording method and 12 recording zone technology. The MHC
Series and MHD Series
have a formatted capacity of 3.25 GB (MHC2032AT,
MHD2032AT), 4.09 GB (MHC2040AT) and 2.16 GB (MHD2021AT)
respectively.
(3) High-speed Transfer rate
The disk drives (the MHC Series and MHD Series) have an internal data rate up to
10.6 MB/s (MHC/D2032AT). The disk drive supports an external data rate up to
33.3 MB/s (U-DMA mode 2).
(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 13 ms (at read).
1.1.2 Adaptability
(1) Power save mode
The power save mode feature for idle operation, stand by and sleep modes makes
The disk drives (the MHC Series and MHD Series) ideal for applications where
power consumption is a factor.
(2) Wide temperature range
The disk drives (the MHC Series and MHD Series) can be used over a wide
temperature range (5°C to 55°C).
(3) Low noise and vibration
In Ready status, the noise of the disk drives (the MHC Series and MHD Series) is
only about 30 dBA (measured at 1 m apart from the drive under the idle mode).
