- To clarify "a bit" for those unfamialr with DAT's and stuff:
-
- The standard DAT sample rate is 48KHz, which offers somewhat trivial
- improvement over the CD standard of 44.1kHz. However, by implementing
- a copy restriction flag on commercial CD's, you are disallowed from mak
- ing direct digital-to-digital copies without constraints even if you are
- able to record at 44.1KHz. Of course, you cannot make direct digital
- copies when the data rates don't match. (i.e. playback 44.1k, record at
- 48k).
-
- HOWEVER, there is a reason for a DAT recorder to be able to record at
- 44.1kHz; That is so that if you are making a "Master" tape to be
- transferred to CD media (For your first Gold album :)), the DAT stereo
- master can be digitally transferred to CD without going thru the analog
- A/D and D/A converters in the playback and recording decks.
-
- Note that by using the analog inputs and outputs of a CD and DAT player,
- there is no copy restriction since the DAT player is no longer receiving
- digital data directly. 'Of course, then that means that you are not
- making a digital copy...
-
- A comment of the proposed DAT tax:
- This was proposed so that blank tapes would have a tax excised that
- would reimburse recording artist for the unavoidable bootleg copies made
- of their works. Since DAT is likely to remain a semi-pro/hobbyist media,
- I don't see this tax having a major consumer impact. (The problem being
- that for semi-Pro use, you shouldn't have to pay tax since you aren't
- bootlegging...)
-
- If you are wondering if DAT is worth it, a recent review of a
- top-of-the-line Nakamichi cassete deck showed it made better
- reproductions of a CD source than a DAT....showing that a high quality,
- properly calibrated cassette deck is still a viable medium.
