mini CD
A CD disc that is 80 mm (3 1/8") in diameter. Mini CDs hold 20 minutes of CD-DA audio compared to 75 minutes for the full-size 120 mm (4 3/4") disc, or 180MB of data compared to 700MB. The mini CD fits into the deeper well in the center of the tray of most CD players and drives.Mini DVDs Are the Same Size
Using the same platter size as the mini CD, mini DVDs hold 1.4GB of video compared to 4.7GB for the regular 120 mm DVD. See DVD.
Beware the Slot Loading Drive
Before inserting a mini CD or mini DVD into the slot of a "feed drive," read the manual. Many feed drives do not accept the smaller platters and can be damaged. However, the small disc can be snapped into an 80-120 mm adapter and then inserted. See business card CD and feed drive.

| How the Drive Holds the Small Discs |

| Laptop optical drives (top two images) use spring-loaded spindles that grasp the inside of the center hole of both the large and small discs. Desktop drives (bottom) have a well in the middle of the tray for the smaller size. |
