I think it makes more sense for the DAT copy-protection to work like this:
DAT can take 44.1 kHz data ==> 48 kHz
^^^
This takes quite a bit of signal processing to do, and would raise the price
of DAT decks a LOT..
DAT will not take 48 kHz data
44.1 kHz is the rate CD's are recorded at, 48 kHz is the DAT rate.
Of course, this method would not let you make DAT-to-DAT tapes of your
daughters first glockenspiel recital, but the record companies don't care
about that!
This, of course, will be the largest problem : My main use for DAT
(when I get hold of one...) will be for music recording/mastering :
Not being able to make (digital) copies would seriously cripple
the usefulness of the system : There is always som editing, etc
to be done..
