徴とする回転ヘツド式テープレコーダ。 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 the rotary head type tape recorder, the error rate counter counts the error rate for each frame independently of the A and B channels during playback, and the error rate of the A and B channels is memorized and compared to find the best error rate. A rotary head tape recorder comprising: an error rate comparison and voltage controller that holds a voltage value; and a voltage generator that uses the controller to generate a voltage that controls the low-pass filters of the A and B channels. .
