US Patent:

7706102, Apr 27, 2010

Filed:

Aug 14, 2006

Appl. No.:

11/504376

Inventors:

Vladimir Gershman - Holland PA, US
Ronald Dean - Marlton NJ, US
Bernard McGrath - Morrisville PA, US

Assignee:

Lockheed Martin Corporation - Bethesda MD

International Classification:

G11B 5/325
G11B 5/024

US Classification:

360118, 360 66, 360137

Abstract:

A hard disk drive includes a chassis which supports a “sealed” housing containing a data storage magnetic disk, and read/write heads and actuator. The housing also contains an erasure device which generates a magnetic or other field or emanation for erasing the disk, so that the erasing field or emanation need not penetrate the sealed housing to effectuate erasure. A backup power supply provides power to the erasing device so that erasure can occur even in the absence of external power. A bus- or network-actuated arrangement couples power to the erasure device so that many hard drives may be simultaneously erased.
