Patent ID: 7153193

Claim:
A system for selectively sensing and removing asperities from hard disk drive media, comprising: at least one test stand supporting said hard disk drive media, said at least one test stand comprising at least one suspension for flying over a surface of said hard disk drive media; a glide pad coupled to one said at least one suspension for said flying over said surface and locating asperities; a PZT sensor coupled to said glide pad for sensing and mapping asperities on said surface of said hard disk drive media; a burnish pad coupled to one said at least one suspension for wearing-away said sensed and mapped asperities on said surface of said hard disk drive media; and a thermal flying height actuator coupled to said burnish pad for protruding said burnish pad when said burnish pad is proximate to one of said mapped asperities, said protruding for facilitating said wearing-away of said one of said mapped asperities.
