Audio digital tapes, also known as digital audio tapes (DAT), are a type of magnetic tape used for recording and storing digital audio signals. Developed in the 1980s, DATs were a popular medium for professional audio recording and production, as they offered high-quality sound and reliable performance. DATs use a helical scan technique to record digital audio signals onto a narrow strip of magnetic tape. The tape is coated with a magnetic material that can be magnetized to represent the digital data. The tape is read and written by a rotating head that moves across the tape at an angle, recording the digital data in diagonal tracks. One of the advantages of DATs is their high storage capacity. They can store up to 120 minutes of stereo audio on a single tape, and up to 240 minutes in extended play mode. DATs also offer high fidelity and low noise, making them ideal for recording and mastering music. However, DATs were not without their limitations. They were relatively expensive compared to other digital audio formats, and required specialized equipment for recording and playback. They also suffered from issues such as dropouts and head clogs, which could result in lost or degraded audio. Despite these limitations, DATs remained a popular format for professional audio recording and production until the early 2000s, when they were largely replaced by digital audio workstations and other digital recording technologies.
