ABSTRACT:
A method and apparatus for detecting and matching the recorded speed of a previously recorded tape. An algorithm changes the commanded speed to a servo system to a speed that is centered between the speed at which the sector header was written and the sector data was written. In particular, the measured synchronization portion of the sector header is initially integrated with respect to time. The measured synchronization portion of the sector data is then integrated with respect to time. An optimum speed is computed based on the difference in the speeds at which they were recorded. The commanded speed to the servo system is then changed as a result of the previous step.
