ABSTRACT:
A data generator assembly for use in retrieving stored data from an information storage medium. The data generator assembly includes a positive peak detector for receiving a preprocessed signal having a predetermined waveform including positive peaks, negative peaks, and a DC component. The positive peak detector is utilized to measure and track the positive peaks to output a positive peak signal. A negative peak detector measures and tracks the negative peaks to output a negative peak signal. The data generator assembly also includes a voltage divider for averaging the negative peak signal and the positive peak signal and generating a threshold signal representing the approximate peak-to-peak midpoint of the preprocessed signal which varies with the DC component. A comparator is provided for comparing the preprocessed signal with the threshold signal. The comparator generates an output data waveform signal indicative of the stored data on information storage medium.
