- That's what I get for saying "Let's be clear." :-)
-
- The point I was trying to make was that SCMS will prevent digital to
- digital copying with DCC anyway (thus making the issue of lossy
- copying irrelevant), but this may only be the overriding restriction
- that I was making it out to be for pre-recorded DCC tapes. If you are
- making your own master tapes with DCC, and then want to make
- digital copies to either DCC or MD, you indeed will go through the lossy
- sub-band encoding/decoding (how's that for a better term than
- "compression"?), just as you said.
-
- I suppose you could copy from DCC to DAT, and then for any number of
- generations of DAT, with only the initial DCC encoding loss (assuming
- the source does not assert copyright). I wonder if there will be
- "professional" DCC decks, analogous to SCMS-free professional DAT
- decks? Seems pointless, given the arguably superior quality of DAT.
-
- Anyway, I'll go on record predicting that DCC will be to CC (analog
- cassette tapes) as CD was to LP, in terms of mass market pre-recorded
- material--"pop music". The sound quality is superior, making the
- artists happy, and the decks are backwards compatible with the
- installed base (all DCC decks will play CC tapes, and probably pretty
- darn good, given the thin-film heads and superior tape transport
- mechanisms), making the majority of consumers happy. The consumer
- audio manufacturers are happy, since they get more product to push.
- Purists and audiophiles have DAT to keep them happy. The only hiccup
- is that Sony will probably force MD down CBS's throat, even though the
- lack of backwards compatibility seems the doom of MD.
-
- The only folks who are unhappy are us poor computer software vendors,
- who don't have the clout to get Congress to pass a tax on floppy disks
- and QIC tapes, to make up for our losses from those nasty software
- pirates! :-)
