Audio Technology / Recording / Recording Devices / DAT recorders...

DAT recorders use magnetic tape as a storage medium. Typical DAT tapes allow the storage of 120 minutes of uncompressed, high-quality mono recording at 48,000 Hz/16-bit. TASCAM DA-P1 (PHOTO>>) offers sophisticated time coding, rugged construction, and a pair of good pre-amplifiers. It also comes with a built-in limiter and microphone/line inputs. It features the S/PIDF digital I/O interface. The migration of digital audio from DAT to a personal computer hard drive for analysis is a lossless process, provided the correct digital transfer interface is used. The DAT tape is as fragile as a regular analog cassette tape, which, again, raises the issue of long-term preservation. Most digital-born recordings stored on DAT tapes will eventually have to be migrated to either spinning disk or optical storage.
