摘要： A sub-ambient pressure, air bearing slider is disclosed for positioning a magnetic read/write head proximately to a rotating disk. The slider includes first and second rails extending along the side of the slider facing the rotating disk from a leading edge of the slider to a trailing edge of the slider. Each rail has a thigh region extending at an angle from the leading edge to a lateral side of the slider, a foot region extending at an angle from a lateral side of the slider toward the trailing edge of the slider, and a knee region at a lateral side of the slider coupled between the foot and thigh regions. Recesses are provided to shape the first and second rails. A central recess provides a volume for sub-ambient pressure. One or more tails can be placed within the central region to prevent the shifting of pressure completely to one side of the slider. The design of the first and second rails leads to a more uniform flying height for the slider and magnetic head over all tracks of the disk.

摘要： A disk drive including voice coil magnet plates formed integrally with the base and/or cover of the disk drive. During the fabrication process, the steel magnet plates are placed in proper position in the base and cover die casting, and then the molten aluminum is injected to form the base and cover. As result, the magnet plates are integral with the base and cover and no fluid leakage can occur around the boundary between the top magnet and cover, or around the boundary between the bottom magnet and base. Thus, the disk drive is sealed against the external environment.

摘要： A data buffer monitor apparatus which monitors the space availability in WRITE buffer and the number of sectors available for transfer in the READ buffer and generates the OK TO TRANSFER signal. The data buffer monitor apparatus includes a READ buffer monitor, a WRITE buffer monitor and a transfer controller. The READ buffer monitor monitors the total number of sectors stored in the READ buffer, the number of sectors in the READ buffer available for transfer to the host and generates a READ OK TO TRANSFER signal if the sectors for a requested READ operation are stored in the READ buffer. The WRITE buffer monitor monitors the total number of sectors in the WRITE buffer and generates a WRITE OK TO TRANSFER signal if the WRITE monitor determines that a requested WRITE operation can be performed. The transfer controller in response to either the READ OK TO TRANSFER signal being generated by the READ buffer monitor if a READ operation has been requested or the WRITE OK TO TRANSFER signal being generated by the WRITE buffer monitor if a WRITE operation has been requested generates an OK TO TRANSFER signal indicating the requested READ or WRITE operation transfer of sectors to and from the disk drive system may be performed by the disk drive.

摘要： A disk drive including a disk clamp for clamping one or more disks within the disk drive. The clamp is comprised of a dual member construction which provides a substantially uniform contact pressure at the circular line of contact between the clamp and the disk. The clamp includes an inner ring surrounding and fixedly attached to the hub of the disk drive. The inner ring preferably does not contact the disk. An outer ring is provided having a first portion underneath the inner ring and a second portion provided axially outward from the inner ring. The second portion of the outer ring contacts the disk in a substantially circular line of contact. The inner ring further includes a plurality of threaded holes, through which a plurality of set screws are provided. The screws, when sufficiently threaded through the holes, exert a pressure on the outer ring, which pressure is uniformly transmitted to the disks to secure the disks within the drive.

摘要： A control system and method for controlling the speed of the spindle motor rotating disks in a disk drive system where the transducers ride or fly upon a medium, air or some other viscous substance between said disks and said transducers thereby exerting a load upon said spindle motor, said load having a non uniform profile across the disks from the inner diameter to the outer diameter of said disks where said load at any location across said disk is a function of the type of medium upon which said transducers rides or files above said disks, said location itself and the physical environment being experienced by said medium at any given instant of time. The control system comprises storage means for storing speed control data for defining the power to be applied to the spindle motor to maintain the spindle motor at a desired speed as a function of the presently selected track address and a control means for selecting the speed control data for a presently selected track address and providing the speed control data to the spindle control system such that the speed of the spindle motor is maintained at the specified speed. The method comprises the steps of a) generating speed data for maintaining the spindle motor at a specified speed as a function of the track being addressed by the disk drive system; b) storing the speed data in a first table in a memory in the disk drive system; c) retrieving the stored speed data for the track presently being addressed by the disk drive system; and d) providing the retrieved speed data to the speed control means for controlling the speed of the spindle motor.

摘要： A disk drive is provided for flying at low flying heights, for example 2 1/2 mu ''. The disk drive includes an adhesive-bonded slider and head suspension design which does not lose its crown or camber with a change in temperature. In a preferred embodiment, the adhesive is applied at discrete points. It was found that applying the adhesive in this manner was sufficient to securely bond the slider to the flexure tongue and resulted in relatively little change in the crown or camber geometry over a wide range of temperatures.
