how long can you keep unused blank cdr media? that is, without using it, and it still keeps its quality? i would consider doing this with 'made in japan' maxell cdr-pros. i've been hearing they may discontinue these?
As long as they are stored in a dark, cool, dry place, keep them as long as you like.
The Maxell Pro discs are nothing but TY CDR's, which you can get anywhere.
