摘要： A suspension arm assembly for a hard disk drive that includes a suspension arm and a thermal adaptor. The thermal adaptor has a thermal coefficient of expansion that is different from the thermal coefficient of expansion of the suspension arm so that a pitch static angle is increased with an increase in temperature. The suspension arm assembly is attached to an actuator arm and coupled to a head of the disk drive. The head may be parked on a landing zone of a disk surface while the disk is stationary. When the disk is spun, an air bearing is formed between the disk surface and the head. If the drive is operating at an elevated temperature the static angle of the suspension arm will increase to increase the slider's pitch angle and air bearing flying height.

摘要： A disk drive includes a drive housing, a storage disk coupled to the drive housing and a head arm assembly coupled to the drive housing. The head arm assembly includes an adjuster and a slider coupled to the adjuster. As provided herein, the adjuster changes the gram load that is applied to the slider as the temperature near the adjuster changes. In one of the embodiments, the adjuster increases the gram load that is applied to the slider as the temperature near the adjuster decreases.

摘要： A disk drive for storing data includes a rotating storage disk and a slider positioned near the storage disk. The slider has a flying side and a read/write head. The flying side includes a leading bearing surface and a leading recessed surface positioned near a leading edge of the slider. The leading bearing surface can include a leading transverse section that is positioned within approximately 20 and 200 microns of the leading edge. The leading recessed surface is positioned between the leading transverse section and the leading edge. The leading bearing surface and the leading recessed surface cooperate to form a relatively high pressure area near the leading edge that facilitates a relatively rapid take-off of the slider away from the storage disk during start up of the disk drive.

摘要： A glide head assembly that can be used to certify disks of hard disk drives. The assembly includes a glide head that is coupled to a suspension arm. The assembly further has a contact sensor coupled to the head. The contact sensor includes a center plate and four beams. The beams are coupled to corresponding sensor elements. Contact between the head and the disk will cause the beams to deflect. The deflection of the beams is sensed by the sensor elements and processed to detect head/disk contact. The number, orientation and amplitude of the beams that are deflected can be processed to determine the pitch and roll angles of the glide head.
