DESCRIPTION

MILPER’s MRDC-20035HA is a rugged, high capacity disk drive designed for use as plug-in unit into MILPER’s MRC family of Rugged Computers, or in any enclosure for standard 5¼“ Device, customer’s enclosure or any other removable mass storage application. The MRDC-20035HA stores up to any Gigabytes of formatted data.

RUGGED DESIGN

Ruggedized for operation in severe environments – where extreme temperatures, shock, vibration, humidity and air pressure are common – the MRDC-20035HA is field proven in “on-the-move” operation in tracked and wheeled vehicles, as well as airborne application. Since warm up time is very short near instant readiness is provided at all operating temperatures. The sealed, housing encompasses the entire drive mechanism, including electronics, isolating the drive from shock and vibration and protecting it from high humidity and changes in altitude. An embedded digital servo system automatically compensates for temperature variation, ensuring accurate, reliable head positioning over the entire operating temperatures range.
To prevent damage during handling and transport, the heads are automatically parked and secured by a locking mechanism when power is removed.

PLUG-IN DESIGN

The interchangeability of Milper’s plug-in disk cartridges allows for simple removal of secure/classified data, easy changes to hardware or operating system configuration, unlimited data storage capacity, and very fast data backup.
