When I look at CDs that I bought from the store, I see that they are a little different than the CD-R I burn myself. First on the back of my cd, we can see where the burn ends, on commercial CDs, it is full all the way even though the CD only has 300 Mb. Also alot of software, windows and Hardware (DVD player, CD player, Consoles) recognizes them as CD-R but not CD-Rom. How can I solve these two issues. PS: I am not into cd copying but I am rather curius, why can they do it and I can’t. My burner is a NEC 7900a 40xread and 24xwrite.
