    摘要: A servo-patterned magnetic recording medium, comprising: a magnetic layer having a surface with substantially uniform topography, the magnetic layer including a data zone and a servo pattern, the servo pattern comprising: (a) a first patterned plurality of regions of first, higher values of magnetic coercivity Hc and magnetic remanence-thickness product Mrt; and (b) a second patterned plurality of ion-implanted regions of second, lower values of Hc. and Mrt; wherein the second, lower values of Hc and Mrt are sufficiently lower than the first, higher values of Hc and Mrt as to permit sensing for enabling accurate positioning of a read/write transducer head in the data zone but sufficiently high for providing the medium with thermal stability, high amplitude of magnetic transition, and high signal-to-noise ratio.

    摘要: The active vibration suppression of a slider suspension arm is achieved by including as part of the suspension arm two bimorph piezoelectric elements. A first bimorph piezoelectric element is attached to the top of the suspension arm and acts as a sensor. A second bimorph piezoelectric element is attached to the bottom of the suspension arm and acts as an actuator. The actuator is controlled as a function of a voltage measured by the sensor so that the actuator damps periodic vibrations occurring in the suspension arm.

    摘要: Disk formatting pattern methods and apparatus are disclosed. The methods feature forming a magnetic disk format information pattern on magnetic disk media by elevating the temperature of a pattern area and exposing the area to a magnetic field. The magnetic field has a field strength sufficient to alter magnetic properties of the elevated temperature region, but insufficient to substantially alter magnetic properties of disk regions at the disk's ambient temperature. A patterning system is also featured. The system includes a light source assembly, a pattern mask, and a magnetic field source. The light source assembly is arranged to project a light beam toward a surface of a magnetic disk. The pattern mask is arranged in the path of the light beam to produce a pattern image on the disk surface, and the magnetic field source produces a magnetic field at disk surface regions receiving the pattern image.

    摘要: A magnetic data storage medium includes a dedicated transducing head contact zone for engaging an air bearing slider, primarily when the disk is stationary. The contact zone is textured with at least one elongate ridge extending in the circumferential direction. When a single ridge is formed, it runs in a spiral path in multiple turns with a predetermined radial pitch at least ten times the nominal ridge width. The ridge protrudes axially outward from a nominal surface plane of the contact zone, and is rounded and free of sharp edges. The ridge, or plurality of ridge sections, can be formed by a texturing process that includes directing a laser beam, focused, onto the contact zone surface. While the disk is rotated to maintain a constant circumferential speed relative to the laser, it also is translated radially to provide the desired radial pitch. The laser is operated in a CW (continuous wave) mode, to create a more uniform ridge.
