ABSTRACT:
A data recording and reproducing circuit for a memory system, such as a magnetic disk memory system. The circuit includes a reflection type cosine equalizer and a data reproducing circuit. The equalizer includes a first equalizing circuit, having a first equalizing gain, and outputting a first equalized signal, and a second equalizing circuit having a second equalizing gain smaller than the first equalizing gain, and outputting a second equalizing circuit. The data reproducing circuit includes a differentiator for differentiating the first equalized signal, a window generating circuit for generating a window signal from the second equalized signal, and a data separator for discriminating the differentiated signal in response to the window signal to produce a pulsed reproduction signal.
