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： The head of a disk drive has write elements disposed on one protrusion pad that wears away during initial operation to permit reduced tolerances and, thus, reduced spacing between the disk and head, with the read element being disposed on a separate protrusion pad and spaced from the write element pad in the radial dimension. This prevents read element recession during cooling in the absence of write current that could otherwise occur if the read element were located on the same pad as the write head.

摘要： A rod formed from a shape memory alloy is stretched under load to reduce its diameter. The rod is positioned in a boss formed in a head gimbal assembly and actuator comb assembly. The rod is heated above its transition temperature such that the diameter of the rod expands to plastically deform and swage the assembly and form a joint. The rod is then cooled to return to its nominal diameter and removed from the swaged assembly.

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 disk texturing tool is used, for example, to provide textured spots in an annular portion of both sides of a hardfile disk. Disks are moved into and out of the texturing process in cassettes, through two disk-handling stations. An optical system includes a laser directed at a beamsplitter to split the laser beam into two beams having approximately equal power, which are directed along parallel paths through a power control optics block to expose simultaneously opposite sides of a disk to be textured. The power control optics block includes means for attenuating and measuring each of the two beams. A shuttling mirror directs these two beams alternately at a disk within each of the two disk handling stations.

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.

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.
