Sensor position adjustment with media velocity relative sample timing

摘要

A system and method for positioning a sensor relative to a storage medium. A system includes a first sensor and a second sensor arranged so that a point of a storage medium traverses each sensor at a different time. A processor is coupled to the sensors. The processor varies the timing of a sample representing a noise signal received from the sensors in accordance with medium velocity. The processor adjusts the position of the sensors based on the sample.
