  • Magnetic disk drive with reduced disk-to-disk spacing and improved actuator design
    Patent number: 5218496
    Abstract: A magnetic disk drive employs a head actuator structure in which the heads are angularly offset from each other around the disk surfaces. This permits the disks to be more closely spaced in an enclosure, thereby resulting in more disk capacity in a given disk enclosure envelope, or a decrease in the enclosure envelope required for a given disk capacity.

  • Disk track for locating zero track and generating timing for index signal
    Patent number: 4949202
    Abstract: A disk drive includes a disk (100) having a plurality of tracks (-2 TO N). The outermost track (-2) includes a first portion (102a) having a data pattern recorded therein that is unique to that track. The data in the first portion is used to determine the location of the outermost track. The outermost track also includes a second portion (102b) including data which is used to indicate the location of a selected sector within each track.
