A Digital Audio Tape (DAT) is a type of magnetic tape used for storing digital audio data. It was introduced in the mid-1980s as a professional audio recording format and was intended to replace the traditional analog audio cassette.
DAT tapes use a helical scan format, which means that the tape is wrapped around a spinning drum and the recording heads move diagonally across the tape. This allows for high-density recording and playback, with data being stored in a linear digital format.
DAT tapes are typically used in professional audio applications, such as studio recordings, radio broadcasts, and live performances. They offer high-quality sound, with a frequency response of up to 20 kHz and a dynamic range of up to 96 decibels.
DAT technology has largely been supplanted by newer digital audio formats, such as CD and MP3, but some professionals still use DAT tapes for archival purposes or as a backup medium.
