摘要： A region of flexure layer, including slider mounting face coupled to offset mounting face for at least one piezoelectric device. The offset mounting face for piezoelectric device provides asymmetry between first contact region and second contact region. This is cost effective, reliable support for piezoelectric devices used for micro-actuation in hard disk drives. The slider moves based upon asymmetry of the offset mounting face coupled to the piezoelectric device twisting the slider mounting face. The invention includes flexure containing the region of the flexure layer. The invention includes head gimbal assembly including flexure, actuator arm including head gimbal assembly, and actuator assembly including actuator arm, and hard disk drive including actuator assembly. The invention includes manufacturing the region, the flexure, the head gimbal assembly, the actuator arm, the actuator assembly and the hard disk drive, as well as these products of the manufacturing processes.

摘要： The present invention is directed towards shock protectors for a pedestal suspended over a lower surface by a plurality of gimbal springs. Each gimbal spring is connected to a linkage arm that attaches to an actuator. A stop located below the bottom of the pedestal prevents the gimbal springs and/or other structures from impacting the lower surface. In addition, the stop prevents excessively high strain in the gimbal springs. A shock absorber extending from at least one linkage arm serves a similar purpose when the pedestal is tilted, rather than simply displaced.

摘要： A method for detecting an asperity in a non-data parking zone of a disk in a hard disk drive. The method includes the steps of moving the heads of the disk drive adjacent to the parking zones of the disks, and then detecting asperities in the parking zones with a thermal asperity detection circuit.
