摘要： An information handling system, such as a disc drive, including a base, a disc stack rotatably attached to the base, and an actuator assembly movably attached to the base. The actuator assembly also includes a load spring and a slider attached to said load spring. The slider has an air-bearing surface. The air-bearing surface includes a first rail, a second rail and a depression positioned between the first rail and the second rail of the air-bearing surface. The depression further includes a first level surface and a second level surface. The first level surface of the slider is at a different distance from a surface of the first rail of the slider than the second level surface of the slider. The air-bearing surface may also include a divider located between the first level surface of the slider and the second level surface of the slider.

摘要： A disc drive includes a base, a disc stack rotatably attached to the base, and an actuator assembly. The actuator assembly also includes a load spring and an attached slider. The slider has an air-bearing surface that a leading edge, a trailing edge, and a center pad positioned near the trailing edge. A transducer is positioned within the center pad. The center pad has a channel cavity therein which is substantially parallel to the trailing edge. The channel cavity is positioned near or at the transition between the material making up the slider and an alumina portion. The channel cavity splits the center pad into a first center pad portion, and a second center pad portion. The width of the channel cavity is controlled to control the amount of movement between a substrate portion of the slider and a portion covering the trailing edge of the slider which results from annealing the slider.

摘要： According to one embodiment of the present invention, a fly height of a read/write head in a disc drive is actively controlled as the read/write head is positioned over a rotating disc with a patterned media. The patterned media includes ridges and grooves in servo wedges in the patterned media. According to another embodiment of the present invention, an estimated fly height of the read/write head is compared with a desired fly height to generate a control signal. The control signal is used to apply a voltage difference across a piezoelectric layer joining the read/write head to a slider to move the read/write head relative to the slider and adjust the fly height of the read/write head. According to another embodiment of the present invention, a map of ridges and grooves in the patterned media is generated and the fly height of the read/write head is actively controlled based on information in the map.

摘要： A disk drive system includes a base, a disk stack rotatably attached to the base, and an actuator assembly movably attached to the base. A ramp assembly includes a set of ramps for loading and unloading the sliders and transducing elements carried by the sliders to and from the disks in the disk stack. The ramp assembly is attached to the base. An actuator assembly is movably attached to the base of the disk drive. The actuator assembly moves the load springs and attached slider and transducers to various positions on the disk. The slider is a block of material having corners and edges. Sliders have a backside surface and an air-bearing surface. The slider also has at least one recess therein. One or more pads of shock absorbing material are positioned within at least one of the recesses in the slider. The pads are positioned within one or more recesses to prevent the corners or edges of the block of material near the air-bearing surface from contacting the disk. In one embodiment, the pads are positioned within the recesses so that the second material is positioned near the air-bearing surface. The pads include a first shock absorbing material, and a second material harder than the shock absorbing material. The second material can be diamond like carbon. After forming the pad, diamond like carbon is deposited on the pad using photolithography.

摘要： The device of the present invention facilitates engaging mating elements, such as actuators used in disc drives, with a pattern on the device. The improved device includes arcuate edges between at least one of the sidewalls in the pattern and the surface of the device. The arcuate edges minimize some of the fracturing of the device that typically occurs when a mating element is inserted on or into the device. The present invention also relates to a method of fabricating a device. The method comprises positioning a mask in the form of a pattern relative to the device, and then etching the pattern into a surface on the device to form at least one sidewall and an arcuate edge such that the arcuate edge extends between the surface on the device and one of the sidewalls.

摘要： A head gimbal assembly (HGA) for use in a forward flow disc drive includes a load beam having a longitudinal axis, a gimbal, a slider, and an air deflector. The gimbal is mounted to a distal end of the load beam. The slider includes a transducing head and is mounted to a disc side of the gimbal and is aligned with the longitudinal axis of the load beam. The air deflector includes a first deflecting member that is positioned upstream of the slider relative to a forward airflow. The air deflector extends from a disc side of either the distal end of the load beam or the gimbal and across the longitudinal axis. The air deflector deflects a portion of the forward airflow away from the slider to thereby reduce windage induced off-track motion of the transducing head.

摘要： A system for keeping the imperfectly machined surfaces of bearings apart at rest. The system includes a first bearing surface which moves facing a second bearing surface, the first surface having a distribution of discrete diamond-like carbon (DLC) pads deposited upon an adhesion layer. The DLC pads are at a height which is approximately the height of the roughness or imperfections of the surfaces. The pads are distributed over the surface at approximately three pads to forty pads or more per square inch. The pads keep the bearing surfaces from coming in contact. Also disclosed is a hydrodynamic bearing having a thrust plate having hydrodynamic grooves and DLC pads on a thrust surface, and a rotor member having an end facing the thrust plate, and a ball and socket bearing having DLC pads deposited on either the socket surface or ball surface.

摘要： A retractable locking pin. The locking pin includes a catch, a biasing means, a stop, a strut and an activation member. The catch is radially respositionable relative to the longitudinal axis of the locking pin as between an outward expanded position and an inward contracted position. The biasing means biases the catch towards the outward expanded position. The stop is longitudinally spaced from the catch and extends radially outward from the longitudinal axis. The strut cooperatively interconnects the biasing means and the stop. The activation member is operably associated with at least one of the catch and the biasing means for repositioning the catch towards the inward contracted position against the bias of the biasing means when the activation member is repositioned in a first direction along a path relative to the stop.
