ABSTRACT:
A servo channel digitally processes the data read from a magnetic media. The channel uses both edges of a system clock to detect peaks and generates position error systems by an area-based automatic gear control loop. By altering the sample delay, the channel digitally, up-samples at higher rates without requiring a higher system clock.
