ABSTRACT:
A crosstalk removing apparatus for digital magnetic reproduction is provided in which a clamp circuit is connected between a playback amplifier and a playback equalizer. An effect of crosstalk from a neighboring track is effectively removed using the clamp circuit including two capacitors, two diodes and a load resistor. The clamp circuit improves a quality of picture of the reproduced signal while maintaining compatibility between recording a reproducing apparatus.
