Abstract
A signal detector of a magnetic disk apparatus has a comparator for generating a pulse signal when an analog signal from a magnetic head for performing the read/write operation of data falls within a range between predetermined voltage levels, a flip-flop for receiving an output signal from the comparator and for generating the signal required in converting a peak of the analog signal to a digital signal, in accordance with the output signal from the comparator, and a gate circuit for supplying a clock pulse to the flip-flop, said clock pulse corresponding to the zero-crossing point of the differential signal for detecting the peak of the analog signal and having a predetermined pulse width, in response to the output signal from the comparator.
