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. In each disk-handling station, a lifter raises each individual disk from the cassette. The individual disk is then transferred to a pick-and-place mechanism, which moves it to a spindle. The spindle spins and translates the disk, so that both sides of the disk are exposed to beams derived from a pulsed laser. The pick-and-place mechanism then returns the disk to the lifter, which lowers it into the cassette pocket from which it was taken. The pick-and-place mechanism simultaneously moves one disk from the lifter to the spindle and another from the spindle to the lifter. While disks are moved by the pick-and-place mechanism of one disk-handling station, a disk in the spindle of the other disk-handling station is exposed to the laser beams.

摘要： A magnetic recording disk with a glass substrate is textured by a process which creates an array of bumps in a magnetic head contact start and stop (CSS) region of the disk. The texturing process uses a laser to provide pulses of predetermined energy fluence on the glass substrate to produce a plurality of raised bumps in the substrate surface, each bump having a surface elevation controllable to within a few nanometers. The bumps are created without unwanted micro-cracking or ejection of surface material by exploiting a narrow operating region below the abrupt thermal shock fluence threshold of the glass substrate. This textured glass substrate provides the magnetic recording disk with improved stiction, wear, coatability and sensor flying height properties.

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 contact start/stop (CSS) magnetic recording disk drive has a highly textured head easier landing zone on the disk and uses a start/stop precedure that minimize both the time the carrier is in contact with the landing zone and the disk rotational speed during contact. The disk landing zone is textured with a pattern of laser-induced bumps that define a surface higher than the surface of the disk data region. At disk drive start-up and power-down, the head carrier exits and enters the landing zone at a predetermined disk rotational speed selected such that the air-bearing surface of the head carrier is still in contact with the surface of the landing zone but is flying in the data region. This limits the amount of time the carrier spends in contact with the textured surface and minimizes the disk speed when it is in contact. The reduced time and speed of carrier-disk contact in the landing zone improves the landing zone durability for any given texture level, which allows a larger level of texturing (and therefore lower stiction) to be used while maintaining adequate landing zone durability (number of CSS cycles without failure). Disk drive actuator control circuitry for start-up and actuator retract circuitry for power-down permit the head carrier to enter the disk data region while flying, even though the disk is not rotating at full speed and thus head servo positioning information is unavailable, and to exit the disk data region only when the disk has decreased to a speed at which the carrier is just capable of flying.
