MILPER‘s MRDC, are rugged, high capacity disk drive designed for use as plug-in unit into MILPER‘s Rugged Computers, Rugged disk enclosure, customer‘s enclosure or any other removable mass storage application. The MRDC-3025 stores 3.08 Gigabytes of formatted data. The unit has an average random seek of 13 msec.

Ruggedized for operation in severe environments - where extreme temperatures, shock, vibration, humidity and air pressure are common - the MRDC-3025 is field proven in ‘‘on-the-move‘‘ operation in airborne application, tracked and wheeled vehicles.

The sealed, aluminum 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.
