オテーププレーヤ。 Standard speed standards for digital audio tapes, in which an audio input signal is sampled, analog-to-digital conversion is performed, and the digital signal is recorded by diagonally scanning it on a magnetic tape using a rotary head. In a digital audio tape player that is capable of playing a low-speed standard in which the tape running speed is 1/2, the cylinder rotates at the same speed as the standard even though it is in the low-speed standard playback mode. means for reading the data twice in the above state and detecting errors in both of the read data; and the data with fewer errors of the two data for which errors have been detected. What is claimed is: 1. A digital audio tape player, characterized in that it is equipped with a means for correcting and correcting errors in the data block by block.
