Credit card disks are approximately the size of a standard business card and hold up to 50 MB of content. They are readable in most CD-ROM drives.
Credit card CD-R disks are the size of the smaller indentation in the tray of your CD-R. Since CD-Rs write from the inner hub outward, you will have no problem writing them on most CD recorders.
Using credit card sized CDs in a slot-loading CD ROM drive (the type that a car CD player uses) can result in a stuck disk. Musicmatch recommends using a standard, tray-loading CD ROM drive to read and write this type of disk.
