- The DAT dispute is settled
-
-
- To music lovers and electronics manufacturers, digital
- audio tape represented a terrific technological leap -- a way
- to make crisp, distortion-free copies of compact discs and
- digital broadcasts. But recording-industry artists and
- executives heard an entirely different tune. To them, DAT would
- dampen compact disc sales, because one CD could be used to make
- countless perfect copies. The upshot of the argument was that
- DAT recorders, sold in Japan and Europe for about two years,
- have been virtually unavailable in the U.S. Now the two sides
- have at last found a way to end their dispute. Result: before
- long Americans will be able to enjoy the superior sounds of DAT
- in homes, in cars or on strolls down the sidewalk.
-
- The agreement between the manufacturers and the recording
- industry states that every DAT recorder will contain a computer
- chip that digitally encodes a signal on the tape when the first
- copy is made. This inaudible code will prevent a machine from
- making subsequent copies of that tape. That way, consumers can
- make a copy of a CD to play in their cars or portable machines,
- but that copy cannot be used to mass-produce more tapes to give
- or sell to other people.
-
- DAT uses the same digital recording technology that
- produces the clear tone of the compact disc. And just as the CD
- sounds better than a regular LP, a DAT tape is a quantum advance
- from a standard audio tape. The DAT tape is also conveniently
- small: 2 3/4 in. long, compared with 4 in. for an ordinary
- cassette. But better sound will initially come at a high price:
- DAT recorders are expected to run at least $1,000, and
- prerecorded tapes could cost more than $25. The recorders, along
- with DAT tapes of everyone from Mozart to Madonna, could start
- appearing in U.S. stores before the end of the year.
