Hitachi GST Assigned Patent

Hitachi Global Storage Technologies, Amsterdam, The Netherlands, has been assigned a patent (8,164,860) developed by four co-inventors for a "servo write robust and good altitude performance ABS."

The co-inventors are Rohit P. Ambekar, Sunnyvale, CA, Nghia Bach, San Jose, CA, Remmelt Pit, Menlo Park, CA, and Oscar J. Ruiz, San Jose, CA.

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A head slider for a disk drive storage device. In general, the head slider should fly at the target height above the disk without crashing onto the hard disk. The head slider has an outside flange that encloses a plateau and an inside flange that encloses a plateau. The two plateaus may have the same surface area or the outside plateau may have a greater surface area. Because of the design of the outside flange, the likelihood that the head slider will crash on the hard disk is reduced."

The patent application was filed on Oct. 20, 2010 (12/908,789).
