- Don't the DCC decks uses the same heads for reading both type of
- tapes? I was wondering if the reason they don't record is because
- these new thin-film (or whatever they are) heads (which are designed
- to read and write the 8 (or 10 or 11 or whatever) track DCC tapes
- can't do a a very good job of recording in the ACC format.
-
- As I understand it (and I don't really understand this so this is mostly
- just a guess), the oxide on DCC tape is very thin, which allows for
- higher density recording, but also requires a much weaker recording
- signal. It makes sense to me these same heads could be used to read
- a normal ACC signal (which is wide enough to span multiple DCC tracks
- and which has a much stronger signal), but that these heads would do
- a very poor job of recording such a track.
-
- If this is true, it would mean adding another head to record ACC tapes,
- and this would make the unit more expensive.
-
- Personally, I don't expect DCC to last more than 6 months. If it had
- come out 3 years ago, before DAT, then it could have found a market.
- But now, with DAT already established, and with MD comming out, I don't
- see how DCC has a chance.
-
- Why would anyone buy DCC? The decks are currently on sale for $999 at
- my local Circuit City. For that much money, you can buy a DAT deck, A
- CD player, a cassette deck, and a Sony walkman. Or, you could buy the
- MD player/recorder and a $300 cassette deck. What does DCC give you
- that you can't get with these other units for the same price?
- Nothing.
-
- For the price of an MD player/recorder, you could also get a DAT deck
- and a CD player, but MD at least gives you some unique features for
- this extra cost that you can't get on any of the other units. You get
- the only consumer media that gives you a file-system structure for
- recording. You get the only consumer media that gives you fast CD-like
- direct access on playback for you own recordings. You get the only
- consumer media that allows you to change the order of tracks after
- recording. You get the smallest consumer hi-fi (:-)) media on the
- market.
-
- DCC vs MD isn't a marketing war like Beta vs VHS was. If Sony failed to
- correctly market the MD - they could loose. But they would really
- have to screw up big time for this.
-
- And I think MD will not only beat out DCC, but it will also replace
- ACC, and in about 3 years, I think MD sales will even pass CD sales.
- MD will never replace CD, but I think MD will replace CD as the primary
- audio distribution format.
-
- The only thing I can see that can stop MD now is if the MD format
- or the players have some type of yet-to-be-seen technical problem
- that makes them unreliable.
