A type of magnetic tape used for the storage or computer data and for sound recording and distribution. Data is stored on a DAT in digital form (unlike a conventional magnetic tape that records in analog form), allowing the high fidelity reproduction of music and other audio. DAT recorders and players are available for home use. Many people in the recording industry insisted that the availability of DAT technology would give "home-taping" the impetus it needed to "kill" music. It didn't.
