Digital signal recording circuit for digital video cassette tape recorder

Abstract

A digital signal recording circuit compensates for the deterioration of a digital signal that occurs during recording and reduces the occurrence of bit errors during playback in a digital signal recording and playback apparatus. The circuit includes a read/write circuit which records and reads digital signals to and from a recording medium and which relays its data to a playback circuit for reproducing digital signals read from the recording medium. The circuit also provides an input signal processing circuit which converts along signals into processed digital signals for recording and a compensation circuit which both amplifies the digital signal for recording and compensates for bit deterioration caused by frequency variations in the processed digital signals.
