DAT (Digital Audio Tape)
Is a standard medium and technology for the digital
recording of audio on
tape at a professional level of quality. A DAT drive is a digital tape recorder
with rotating heads similar to those found in a video deck. Most DAT drives can
record at sample rates
of 44.1 kHz, the
CD audio standard, and 48 kHz. DAT has become the standard archiving technology
in professional and semi-professional recording environments for master
recordings. Digital inputs and outputs on professional DAT decks allow the user
to transfer recordings from the DAT tape to an audio workstation for precise
editing. The compact size and low cost of the DAT medium makes it an excellent
way to compile the recordings that are going to be used to create a CD master.
As an
archiving medium, DAT is an alternative to consider along with:
Digital Data Storage
(DDS1 through DDS3)
VHS tape
DAT Tape
Acronym
for digital audiotape, a type of magnetic
tape that uses a scheme called helical scan to record data.
A DAT cartridge is slightly larger than a credit card
in width and height and contains a magnetic tape that can hold from 2 to 24 gigabytes
of data. It can support data transfer rates of about 2 MBps.
Like other types of tapes, DATs are sequential-access media.
