摘要： To allow for adjusting the fly height of a read/write head carried by a slider, a shear transducer is added to the slider. The shear transducer comprises a layer of piezoelectric material added to the slider so that the portion of the slider carrying the read/write head can be moved when the shear transducer is sheared. To cause the shear transducer to shear, a voltage is applied across the piezoelectric layer. To control the movement of the transducer, a closed-loop control system is used. The control system senses the spacing between the read/write head and the disc surface, compares the sensed spacing to a desired spacing, and adjusts the voltage applied to the shear transducer to reduce the difference between the actual and desired spacing.

摘要： A read/write head microactuator includes first and second insulating deposits that are flat, spaced apart by an air gap, and laterally movable responsive to a microactuator electrical drive current. First and second flat, interdigitated drive electrode deposits are deposited on the first insulating deposit. A flat, digitated sense electrode deposit is deposited on the second insulating deposit. The sense electrode deposit provides a relative position output. The sense electrode deposit faces both the drive electrode deposits across the air gap.

摘要： A disc drive that includes a slider with a field emission sensor that senses fly height. The sensor has an electrode tip disposed on the slider. The electrode tip faces a media surface across a gap. The sensor conducts a tunneling current through the gap and provides an output representing the length of the gap. An actuator adjusts the fly height spacing. A feedback circuit provides an actuator electrical input as a feedback function of the sensor output to control the fly height spacing.

摘要： A method of handling a wafer for through-wafer plasma etching includes lateral support provided between a handle wafer and a product wafer without wafer bonding or an adhesive film using mating mechanical structures. The product wafer is easily separated from the handle wafer following etching without stripping or cleaning. Because the connection between the wafers is mechanical, not from an adhesive layer/bonded layer, a wafer can be etched, inspected, and subsequently continue to be etched without the hindrance of repeated bonding, separation, and cleaning. A non-bonded support for released devices following a through-etch process is also provided.

摘要： A sealed micro-actuator device for positioning a slider in a disc drive comprises a micro-actuator body, which includes a stator, a rotor, and a motor for moving the rotor with respect to the stator. The micro-actuator device includes means for sealing the micro-actuator body to prevent debris from reaching the motor. In a preferred embodiment, the means for sealing comprises a plurality of cavities formed in the micro-actuator body and an injection molded polymer seal with a plurality of protrusions that extend into the plurality of cavities. A first subset of the plurality of protrusions make contact with the stator, thereby holding the means for sealing in place. A second subset of the plurality of protrusions extend into cavities formed in the rotor. The second subset of protrusions does not contact the rotor. In an alternative preferred embodiment, a first and a second surface of the rotor are recessed from a first and a second surface of the stator, and the means for sealing comprises a first flexible film heat sealed to the first surface of the stator and a second flexible film heat sealed to the second surface of the stator. In another alternative embodiment, a sealed actuator is incorporated into a slider of a disc drive. The slider comprises a slider body, a data transfer element, and an actuator. The data transfer element transfers data to or from a magnetic medium. The actuator is coupled between the slider body and the data transfer element. The actuator is operable to move the data transfer element relative to the slider body. The slider includes sealing means to prevent debris from reaching the actuator.
