ABSTRACT:
A read circuit for a floppy disk drive is disclosed. The circuit comprises a read head for generating an electrical signal corresponding to recorded data, plus an amplifier, equalizing filter, low pass filter and decoder for processing the electrical signal. The equalizing filter has a response, in the frequency domain, determined by the Laplace transform: ##EQU1##
