Abstract
A peak detection circuit receives a playback signal from a magnetic storage medium and generates a peak detection signal. A shift register transmits the peak detection signal, and a pattern detection circuit is responsive to signals from the shift register to detect a first predetermined temporal pattern of peaks in the peak detection signal. A pattern correction circuit adjusts the relative timing of peaks in the peak detection signal so that the first predetermined temporal pattern of peaks in the peak detection signal is converted to a second predetermined temporal pattern of peaks in a corrected peak detection signal.
