摘要： A suspension assembly for supporting a read/write head/slider assembly adjacent to a rotating storage disk with dynamically adjustable flying height for use within a hard disk drive is provided. The suspension assembly includes a generally elongated loadbeam that has a baseplate defined at a first end thereof and a gimbaled flexure portion defined at a second end thereof. The flexure portion includes a pair of flexure legs and a flexure tongue. The pair of flexure legs extend from the flexure tongue and each leg attaches to an opposite side of the loadbeam. The flexure tongue generally provides a mounting surface for the read/write head/slider assembly. Strips of thermal-expansion material are attached to the flexure portion. These strips are connected to a power source via a power conductor. When the strips are energized, they expand and deform a portion of the flexure portion. This deformation of the flexure portion is transposed to the read/write head/slider assembly for dynamically adjusting the flying height thereof.

摘要： An improved flexure for supporting a read/write head adjacent to a relatively moving storage medium in a disk drive is disclosed. The flexure is a patterned flex circuit structure that is mounted to a load beam in an actuator assembly and includes integral wiring and bonding pads for electrically connecting the head to the electronics of the disk drive. The flexure also implements a high compliance gimbal with integral wiring.

摘要： A disk drive head-gimbal assembly includes a flexure that is modified to address the effects that the operating temperature of the disk drive may have on fly height. Generally, the flexure tongue is split into a leading edge flexure tongue section and a trailing edge flexure tongue section that are separated by a slider decoupling section. The slider decoupling section structurally interconnects the leading and trailing edge flexure tongue section, and further provides a reduced contact area with the slider. This reduced contact limits the ability of the flexure tongue to induce a positive crown on the air bearing surface of the slider.

摘要： A disk drive includes a rotatable data storage disk and a vane positioned adjacent to the disk that receives airflow generated during rotation of the disk. A sensor is operably coupled to the vane and measures airflow force on the vane. Because of a known relationship between altitude and airflow force, the amount of airflow force on the vane is indicative of altitude of the disk drive. The sensor provides an output signal that is indicative of measured airflow force on the vane. The vane surface may be oriented substantially orthogonal to a plane of the disk or substantially parallel with a plane of the disk.

摘要： An improved suspension for supporting a read/write head adjacent to a relatively moving storage medium in a disk drive is disclosed. The suspension includes a curved loadbeam or a curved flexure that reduces the magnitude of the gain in the first torsion resonant mode of oscillation when the Z-height of the loadbeam is configured for minimum sensitivity of the first torsion gain as a function the loadbeam Z-height, thereby providing a suspension capable of providing improved head position servo performance and improved manufacturing and assembly yields.

摘要： A disk drive includes a drive circuitry, a storage disk, a suspension and a slider. The slider is supported by the suspension and receives electrical current from the drive circuitry. The slider includes a flying side that generally faces the storage disk, a read/write head, and a slider deformer that is electrically decoupled from the drive circuitry. In one embodiment, the slider deformer is formed from a material having a coefficient of thermal expansion that is greater than a coefficient of thermal expansion of other portions of the slider. In this embodiment, the slider deformer causes a deformation of a portion of the flying side when the temperature of the slider deformer changes. Thus, when the read/write head expands or contracts due to a change in temperature of the slider, the slider deformer at least partially offsets the expansion and/or contraction of the read/write head to maintain a substantially consistent head-to-disk spacing of the disk drive.
