    摘要： A method of swaging a head gimbal assembly (HGA) to an actuator arm comprises positioning a tubular element on the HGA adjacent a hole in the actuator arm; restraining the subassembly; providing a rod formed from a shape memory alloy (SMA), the SMA having a martensitic phase at a low temperature and an austenitic phase above a phase transition temperature that is higher than the low temperature, the rod having an initial diameter that is smaller than diameters of the tubular element and the hole; extending the rod through the tubular element and hole; heating the rod above the phase transition temperature such that the rod expands to a second diameter that is greater than the initial diameter to plastically deform the HGA and swage together the HGA and actuator arm to form an assembly; cooling the rod and removing the rod from the assembly such that the rod returns to the initial diameter.

    摘要： A multichannel acousto-optic modulator (MCAOM) is described which uses a crystal with a plurality of mounting faces for acoustic transducers. The mounting faces are oriented so that the acoustic transducers mounted thereon generate acoustic fields which intersect the incident laser beam at a common angle, i.e., the Bragg angle. A two channel MCAOM uses two transducers. Extension to any higher number of channels follows accordingly. Energizing any of the transducers causes a corresponding first order beam to be diffracted out. Since the acoustic field for each transducer intersects the incident beam with a unique orientation, each first order beam is diffracted out on a unique axis. A system utilizing an MCAOM has electronic means for controlling the driving signals to the transducers to control each channel as required by the application. Amplitude and frequency modulation of the driving signals allows the intensity and angle of the beams to be controlled.

    摘要： A data recording disk having at least part of the data storage surface textured according to a process for creating a "distant bump array" surface texture for reducing stiction. The texturing process uses a tightly focused diode-pumped Nd:YLF or Nd:YVO.sub.4 or other solid-state laser that is pulsed with a 0.3-90 nanosecond pulse train to produce a plurality of distantly-spaced bumps in the disk surface. The bump profile can be selected as a smooth dimple or one with a central protrusion useful for low stiction without close spacing or elevated "roughness". The data-storage region of the disk surface can be textured for low stiction without materially affecting magnetic data storage density.

    摘要： A method for simultaneously measuring contact potential and slider body clearance in a hard disk drive. In embodiments of the present invention, a plurality of direct current (DC) pulses are applied between a slider body and a hard disk of a magnetic disk drive. The contact potential voltage between the slider body and the hard disk is determined in response to applying the plurality of direct current (DC) pulses. The voltage of the plurality of direct current (DC) pulses is increased until a contact between the slider body and the hard disk is detected.

    摘要： A process for creating a "distant bump array" surface texture in a magnetic recording disk for reducing stiction and the disk so textured. The texturing process uses a tightly focused diode-pumped Nd:YLF or Nd:YVO.sub.4 or other solid-state laser that is pulsed with a 0.3-90 nanosecond pulse train to produce a plurality of distantly-spaced bumps in the disk surface. The bump creation process is highly controllable, permitting repeated creation of a preselected bump profile such as a smooth dimple or one with a central protrusion useful for low stiction without close spacing or elevated "roughness". Some bump profiles permit texturing of the data-storage region of the disk surface for low stiction without materially affecting magnetic data storage density.
