Abstract
A read post compensator circuit for a magnetic record/reproduce device comprises a transducer for reading a sequence of magnetically coded data bits from a magnetic medium and generating an electrical signal representative of the data bits, having a sequence of peak values corresponding to the data bits and having variable time intervals between successive peak values. The circuit has a peak detector to detect the peak values of the electrical signal and a time domain filter for generating output data bits corresponding to detected peak values of the electrical signal and for dynamically varying the interval between successive output data bits in direct relation to the time interval between corresponding peak values to automatically compensate for peak shifting of the electrical signal.
