While rotating the two heads, the digital audio data read from the magnetic tape is stored in the memory, and when the heads are not reading audio data from the magnetic tape, the processor reads the audio data from the memory and stores it in a predetermined manner. In a reading signal return generation device for a digital audio tape device that performs processing, means for generating a head switching signal when the head reaches a predetermined rotation angle before a reading start position at which audio data can be read from a magnetic tape; A pulse generator that generates a pulse every predetermined angle rotation; and N 1 and N 2 (N 1 < N 2 ) pulses generated by the pulse generator after the head switching signal is generated by the head switching means. The period from counting N 1 pulses to counting N 2 pulses is a period in which the head is reading audio data from the magnetic tape, and the period other than that is a period in which the head is reading audio data from the magnetic tape. 1. A reading signal generating device comprising means for generating a reading signal during a period in which audio data is not being read.
