| 摘要 | Methods for determining a variable data frequency for recording data on a zone of a magnetic storage disc, each zone including a plurality of tracks and each track including a plurality of sectors, the method includes measuring a signal to noise ratio (S/N) around at least a first track in a first zone; and modulating a data frequency based on the measured S/N around the first track. | ||
