とを特徴とするＤＡＴ装置。[Claim for Utility Model Registration] A dubbing possible/impossible determining unit that determines whether digital dubbing is possible or not based on control data included in externally input digital audio data during digital dubbing; An AD converter that converts signals to digital, a DA converter that converts digital audio data to analog, and when digital dubbing is not possible, digital data obtained by converting digital audio data to analog and then converting it to digital. It is characterized by having a signal processing section that performs signal processing on the data and records it on a DAT tape, and when digital dubbing is possible, records it on a DAT tape based on input digital audio data without AD or DA conversion. DAT device.
