Audio Or Data Cdr's ????

[George]

Does anybody out there have a clue as to why Mitsui would market both Audio and Data cdr's if they are apparantly the same. They appear to be the same where cdg's are concerned. Reason I ask is because I used Mitsui Audio cdr's exclusively for a long time, and when MTU started carrying Mitsui Media I placed an order with them. Got rather upset when they came in as Data cdr's not audio, but was assured by MTU they would do just fine which they do. So what's the difference ?

Still curious,

George
