イジタルオーデイオテーププレーヤ。 Standard speed standards for digital audio tapes, which sample audio input signals, perform analog-to-digital conversion, and record the digital signals by diagonally scanning them on a magnetic tape using a rotating head, and the number of rotations of the cylinder and In a digital audio tape player that is capable of playing back both the tape running speed and the low speed standard set at 1/2, the cylinder runs at the same speed as the standard speed standard even though it is in the low speed standard playback mode. A digital audio tape player characterized in that it comprises means for rotating, and means for inhibiting the reproduction output every one rotation of the cylinder in the above state.
