Abstract

PURPOSE: To correct accurately a recording equalizer with a few bits by providing a fixed equalizer switching corresponding to the kind of a tape and a variable equalizer for equalizer correction.
CONSTITUTION: The output of reference signal oscillation part 2 is passed through recording equalizer 4 capable of varying an equalization value and then passed through fixed recording equalizer 5 of characteristics corresponding to the kind of a tape with switches 6 to 8 selected, and after they are recorded on tape 10 by recording head 9, data on the tape are regenerated by regenerating head 11. The regenerated signal is inputted to AD converter 15 by way of regenerative equalizer 12 with fixed characteristics selected by switch 13 and detection and sample holding circuit 14. Control part 3 controls equalizer 4 by an AD-converted value to the reproduction output of a fixed value. This operation is performed while changing the frequency of oscillation part 2 so as to obtain nearly-flat recording regenerative frequency characteristics over the whole frequency band.
