Abstract
A method and apparatus are provided for digitally correcting sector pulse placement in a direct access storage device. A sector clock signal is generated equal to a sub-multiple clock rate of a predetermined servo identification clock. An individual servo identification field location is identified and compared with an expected location of said individual servo identification field to identify an error value. The sector clock signal is modified by adding or subtracting clock pulses responsive to the identified error value for generating a sector pulse.
