Claims

[Scope of utility model registration request]

Recording is performed while forming an inclined track on the tape by two rotating heads A and B, and a playback signal is obtained by performing tracking such that the rotating head scans over this track during playback. In a rotary head tape recorder, two band pass filters extract different arbitrary frequencies from the playback signal during playback, two sample and hold circuits hold the level of the frequencies, and the level held by the sample and hold circuits. A level comparison and voltage controller that compares and holds the voltage value that gives the best level difference;
, a voltage generator that generates a voltage for controlling a low-pass filter of a B channel.
