摘要： A disk drive system includes a base, a disk rotably attached to the base, and an actuator assembly movably attached to the base. The actuator assembly moves the transducer to selected areas of the disk where information reprexentative of data is to be written or read. The actuator assembly maintains the transducer in a transducing relationship with the disk. The actuator assembly also parks the transducer or unloads the transducer to a park position. A portion of the actuator assembly rides over a ramp to a park position. The ramp includes a mechanism for increasing the coefficient of friction on the surface of the ramp. The coefficient of friction on the surface of the ramp is increased to help retain the actuator in its parked position. This helps maintain the actuator assembly in a parked position in the event of shock loading from dropping a computer or a disk drive. This in turn helps prevent head crashes or failure of the disk drive and possible data loss.

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.

The actuator assembly maintains the transducer in a transducing relationship with the disk. The actuator assembly also parks the transducer or unloads the transducer to a park position. A portion of the actuator assembly rides over a ramp to a park position. The ramp includes a mechanism for varying the coefficient of friction on the surface of the ramp. The ramp has a lower coefficient of friction when the actuator is unloading the transducer from the disk. When the actuator is placed in a park position, the coefficient of friction on the surface of the ramp is increased to help retain the actuator in its parked position. This helps maintain the actuator assembly in a parked position in the event of shock loading from dropping a computer or a disk drive. This in turn helps prevent head crashes or failure of the disk drive and possible data loss.

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.
