[Claim for Utility Model Registration] An ATF area is recorded at the beginning and end of a track recorded diagonally on a magnetic tape, a pilot signal is placed in the ATF area, and a sync signal is used to set the sampling timing of the pilot signal. The crosstalk components of the pilot signals of the left and right adjacent tracks are sampled according to the timing of detecting the sync signal with a rotating head whose head width is larger than the track width, and the levels of the crosstalk components are compared and detected. In a tracking control circuit of a rotary head type digital audio tape recorder, the level difference is supplied as a tracking error signal to a capstan motor control section. A rotary head type digital audio device characterized in that an adder circuit is provided between a sampling circuit that outputs an output to a capstan servo circuit and a capstan servo circuit, and a voltage generating circuit is provided that outputs a constant voltage to the adder circuit during tracking control driving. Tracking control circuit for tape recorder.
