[sci.electronics] CDs with 3000Hz notch

It will be interesting to see how the record companies are going to
add this new CD feature.  If they tell people ahead of time, the price
of non-notched CDs will rise dramatically (can you imagine the resale
value of a non-notched CD when the notched CD has an audible and possibly
bothersome notch).  Maybe this way the record companies can produce
2 versions of each CD, one with notch (costing $14.00 each), and one without
notch (>> $14.00 each).  I also wonder if there will be any marks on
CDs that are notched.  How does one know?  Are they already notched??
Anyone have a spectrum analyzer handy?
