Lockheed Martin Assigned Patent

Lockheed Martin Corp., Bethesda, MD has been assigned a patent (8,213,115) developed by Vladimir Gershman, Holland, PA, Ronald Dean, Marlton, NJ, and Bernard McGrath, Morrisville, PA, for a "secure data storage".

The abstract of the patent published by the U.S. Patent and Trademark Office states: "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."

The patent application was filed on March 5, 2010 (12/717,999).
