1.1.2 Features - Fujitsu M2361A Customer Engineering Manual

1.1.2 Features
(1) Large capacity and high performance
- 689 megabytes of unformatted data can be stored on six disks.
- The M2361A disk drive provides exceedingly high performance
characteristics such as 2.458 megabytes per second data transfer, 18
milliseconds average access time, and 8.33 milliseconds average latency
time.
(2) Compact size
The disk drive unit configured with Disk Enclosure (DE), DC -power supply
and LSI circuits, is available for mounting in a standard 19-inch rack.
(3) High reliability
The disk enclosure includes a rotary actuator, a direct-drive spindle
motor, the magnetic heads, disks and carriage. A completely sealed
self-contained airflow system is used within the DE to assure a clean
environment for low-flying heads, thus ensuring very high reliability.
(4) High serviceability
The DE can easily be re~oved for replacement in the field by CE.
- The display panel appears when the sub-panel is opened.
This panel allows;
· Drive address settina
· Drive status display
· Drive sector count setting
As a result, except for parts replacement, the drive need not be pulled
out from the 19" rack.
(5) Maintenance-free
The M2361A disk drive requires substantially reduced maintenance because
of the completely sealed DE, a direct-drive DC spindle motor and highly
reliable printed circuit boards.
(6) Auto actuator lock
The rotary actuator is locked by means of a plunger magnet to prevent the
head from moving across the disk surface during transportation. The
plunger magnet unlocks automatically immediately after the AC power is
supplied.
(7) Other features
1 - 2
- High recording density with state-of-the-art technology
A recording density of more than 10
7
bits per square inch is achieved
with the advanced head and disk.
- Low power consumption
Less than 0.64 KVA is required despite the large storage capacity.
