Disk drive head positioner with thin-film air-flow adjusting mechanism, thin film member and method of manufacturing

摘要

A disk drive ( 10 ) includes a plurality of thin-film members ( 36 ) for respectively covering the desired contour portions in a plurality of suspension arms ( 26 ) of an actuator ( 20 ). Each thin-film member ( 36 ) is fixedly attached to the surface of the suspension arm to cover the contour portion around a through hole ( 34 ) formed in the corresponding suspension arm ( 26 ) for reducing the moment of inertia, so as to cover the through hole. The thin-film member ( 36 ) substantially makes the contour portion around the through hole of the suspension arm ( 26 ) flush, and the air flow caused around the storage disks ( 16 ) rotating at high speed is guided smoothly along this contour portion. As a result, the air flow is stabilized, and the influences such as vibration on the actuator ( 20 ) are suppressed.
