A digital tape recorder is a tape recorder that uses digital technology for recording and playback.

A digital tape recorder is a tape recorder that uses digital technology for recording and playback. It can be divided into two types: rotary magnetic head type and fixed magnetic head type. The rotary head type uses a pulse code modulation (PCM) processor to convert the analog audio signal into a digital signal and then converts it into a pseudo video signal, and then records it with a U-matic or professional VHS recorder. The fixed head type is mostly a multi-track machine. There are two-channel 12-track machine and 16-channel, 24-channel, and 32-channel machine. They are divided into PD format and DASH format, which are not compatible with each other.

The Compact Cassette Rotary Head Digital Recorder (DAT) is a model that combines a PCM processor with a rotary head recorder. It has a small size and is portable for mobile recording. A small cassette fixed head digital recorder (DCC) is a digital cassette recorder that is the same size as a normal cassette and can also play back ordinary analog cassettes. It uses a precision adaptive sub-band coding (PASC) system, which uses the human ear's hearing characteristics to greatly reduce the bit rate. The digital tape recorder has a dynamic range and a signal-to-noise ratio of more than 90dB, no jitter, a frequency response of 20Hz to 20KHz, and beautiful sound quality.
