Hello Otto: Most CD come as 700 mg / 80 minutes. That means you can put 700 mg of data or you can put 80 minutes of music. If you are looking for software to create CD/DVDs Priemer software www.readingmadeeasy.com has one which is deisgned for easier navigation for the blind ($60).

Thanks to all in advance. Otto
