i use to use mini disc, think they're quality! loads better than CD
but i used to just copy all my CD's to mini disc then keep the mini discs in the car n the CD originals in the home (that way if ya car gets broke into you dont lose all ya CD collection)
mini discs so much better cos you dont need to keep them in a case
can chuck em about n they dont break
program all track names in to em
n they loads smaller
