    摘要: A hard disk drive that includes a disk, a head, and a filter enclosed by a base plate and a cover plate. The base plate has a filter wall with a fore end and an aft end. The fore end of the filter wall has a tapered surface that extends to an apex. The distal end of the filter wall has a first filter attachment portion separated from a second filter attachment portion by a groove. The second filter attachment portion may be longer than the first filter attachment portion. The filter wall induces a flow of air that inhibits particle attachment to a reverse side of the filter.

    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 based upon notch and slot. 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 invention includes a disk damper containing an extended area located on the upstream side of the head stack assembly. The extended area is joined to a tail section. In the extended area, the disk damper provides a wall near the neighboring rotating disk surface that extends from the outside diameter to the inside diameter of the rotating disk surface. Experimental results have shown that this provides much more consistent dampening of disk vibrations and vibrations of a head stack assembly positioned anywhere from the inside diameter to the outside diameter. The hard disk drive including the disk damper. Using the disk damper in a hard disk drive to improve the reliability of the hard disk drive during track following. Making the hard disk drive using the disk damper, and the hard disk drive as a product of that manufacturing process.

    摘要: A hard disk drive that includes an optical pick-up coupled to a head of a hard disk assembly (“HDA”). The head is located adjacent to a disk. The optical pick-up can sense the surface of the disk by detecting light reflected from the surface. The optical pick-up is coupled to a particle circuit that can distinguish between an embedded particle and a floating particle from the reflected light.
