DAT Stuff Follows:

That was the original plan, but the companies producing DATs would not give in
so according to Stereo Review the latest protection is done like I said
in my earlier post.  All the new DATs will be able to record at the sample
rate of CD players, and take direct digital input.  The real kicker to all
of this is at least two of the DAT manufacturers have copy protection
bypass in their top players, and no one is complaining. (Nakamichi & HK)

So in summary:

DAT->DAT One Digital Copy Only (Prerecorded)
CD->DAT  Unlimited Digital Copies
CD->DAT->DAT One Digital Copy Only, and No Copies of the Copy.

And the new protection does use an extra bit, so there is no loss of
sound quality like was in the original DAT protection.
