  • Using a mechanical stop for determining an operating parameter of a data handling device
    Patent number: 7397623
    Abstract: Several readings of an actuator's location are taken with a given head while urging the actuator against a mechanical stop, which acts as a guide. These readings are useful, for example, for estimating certain offsets or for determining a nominal track range for a data surface.
    Type: Grant
    Filed: October 14, 2003
    Date of Patent: July 8, 2008
    Assignee: Seagate Technology LLC
    Inventors: EikFun Khor, WingKong Chiang, KianKeong Ooi, June Christian Ang
  • Determining a location based on a cyclic bit sequence containing consecutively-placed identical bit-groups
    Patent number: 7242546
    Abstract: A location within a cycle is determined by reading a portion of a cyclic bit sequence, the bit sequence containing several interspersed bit-group sets that each contain a plurality of series that each consist of several consecutively-placed identical bit-groups. On a data surface in a disc drive, each bit group can be stored and accessed in unused bits of each servo sector's digital portion.
