    摘要： A head or slider having a sensor element to detect changes in head-media spacing is disclosed. In illustrated embodiments the sensor element includes a piezoelectric sensor layer or similar layer that provides acoustic emission or vibration responsive to changes in head-media spacing. In illustrated embodiments, the sensor element is located proximate to the close point of the head and slider. In embodiments described in the specification, output from the sensor element is utilized to energize a heating element or microactuator to control pole tip protrusion or actuation of transducer elements responsive to changes in head-media spacing.

    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 rotatably 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 representative 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 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： A head assembly having a sensor element on the head assembly. Embodiments of the sensor element are configured to detect non-contact induced head-media interface instability, “onset of contact” or low level interference. The non-contact head-media instability or interference is detected based upon sensor feedback relating to excitation of the air bearing resonance modes of the slider body. In embodiments of the present invention, the sensor head assembly includes a microactuator which is energizable to microactuate the head or transducer elements on the head assembly.

    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.
