ABSTRACT:
An integrated system for use in a disk drive system for the implementation of write precompensation for recording of data and read window margining for accelerated testing of the disk drive. Both functions are provided by a common delay-line circuitry. The output of the delay line circuit is applied to both window shifting and write precompensation. An on-board read detection error analysis can be performed after installation of the drive in a computer system in its final configuration. Actual read error tolerance based on the overall system in its actual operating condition can thus be obtained. Enhanced data recovery techniques are also facilitated.
