ルオーデイオテープレコーダ。[Claims for Utility Model Registration] A digital tape recorder in which recording is performed by alternately forming inclined recording tracks on a magnetic tape by first and second rotating magnetic heads having different head gap azimuth angles. In this method, double azimuth heads constituting third and fourth rotating magnetic heads having the same head gap azimuth angle as the first and second magnetic heads are connected to the first and second rotating magnetic heads. The third and fourth rotary magnetic heads output reproduction signals each time the double azimuth head scans the pair of inclined recording tracks. A digital audio tape recorder comprising: a switch circuit that alternately selects an audio signal; and a signal processing circuit that processes the selected playback signal to obtain an audio signal for monitoring.
