摘要： An electrostatic actuator for adjusting a spacing. A first body has an electrically conducting surface, and a second body has a body surface separated by the spacing from the electrically conducting surface. A conductor layer and an actuator electrode are recessed in the second body, and an electrode face faces the electrically conducting surface across the spacing. The actuator electrode comprises a semi-insulating material with a combination of electrical resistivity and thickness which prevents shorting of the conductor layer to the electrical conducting surface through a dielectric breakdown in the spacing.

摘要： Herein is disclosed a method and apparatus for reducing particle collection on a slider or gimbal tongue. The gimbal tongue is shaped so as to interact with airflow within a disc drive to direct particles away from the slider and gimbal tongue. The leading edge of the gimbal tongue overhangs the leading edge of the slider. As air current approaches such a geometry, a large pocket of slow moving, high pressure air is created just upwind of the slider. Thus, as particulate matter encounters this pocket, the matter is slowed and its momentum is partially dissipated. A vent is provided in the gimbal tongue. The vent permits an escape route for the particles to move to an area of lower pressure, located on the other side of the gimbal tongue.
摘要翻译：本文公开了用于减少滑块或万向节舌上的颗粒收集的方法和装置。万向节舌片成形为与盘驱动器内的气流相互作用，以使颗粒远离滑块和万向节舌头。万向节舌的前缘突出于滑块的前缘。当气流接近这样的几何形状时，刚好在滑块的上风中产生一个缓慢移动的高压空气的大口袋。因此，随着颗粒物碰到这个口袋，事情变得缓慢，其动量被部分耗散。在万向节舌头上设有通风口。排气口允许颗粒移动到位于万向节舌头另一侧的较低压力区域的逃生路线。

摘要： The slider and method of the present invention relate to a slider for a disc drive. The slider includes a substrate having a cavity and a filler within the cavity. The slider further includes a transducer that is positioned near the filler. The design facilitates controlling the relative thermal expansion between the transducer and substrate of the slider that is near the transducer. Compensating for the thermal expansion of the transducer provides a more consistent fly height of the slider during operation of the disc drive. In addition, the design adjusts the air-bearing surface of the slider such that the transducer does not extend below the rest of the slider as the transducer expands.

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.
