  • Identification of defective servo information elements in a disc drive system
    Patent number: 6392831
    Abstract: A method and disc drive system identify defective servo information elements on a disc. Servo information elements are read from the track on the disc to receive first servo data status values associated with the servo information elements. If the first servo data status value associated with a first servo information element fails to satisfy a first predetermined criterion, the first servo information element is identified as a suspected servo information element. Location and error type information associated with the suspected servo information element is recorded in a hit table. The servo information elements from the track on the disc are reread with a second servo information element masked, and second servo data status values for the servo information elements are received.
