The Apple CD Caddy is the plastic case that holds a compact disc in Apple's caddy-loading CD-ROM drives. The drive never takes a bare disc: the disc goes into the caddy, and the caddy into the drive.[1] Apple's specifications for the AppleCD SC, AppleCD SC Plus, AppleCD 150 and AppleCD 300 give the playback medium as a 12 cm optical disc installed in a CD caddy, any CD-ROM or audio CD.[2][3] One caddy came with each AppleCD SC and SC Plus, and Apple sold spares in boxes of five, order number M2705.[2][4]
When the caddy goes into the drive, a metal shutter on it slides back to expose part of the disc to the drive's optical head. Apple's owner's guide gives protection of the disc as the reason for the design, and suggests keeping discs in caddies when they are not in use.[1]
Loading a disc
[edit | edit source].png)
- Open the caddy. Its lid is hinged like a cigar box: press in on the sides of the case where it is marked Open, with the thumb and a finger of one hand, and lift the clear lid with the other hand.[1]
- Put the disc in label side up, holding it by the edges. Tip the leading edge down slightly as it goes in so that it does not catch on the ledge of the caddy, then close the lid.[1]
- Make sure the disc lies flat and fully down in the caddy. If it does not, the drive cannot read it.[1]
Apple's support article explains why the last step matters. A disc that is not flush with the bottom of the caddy stops the caddy door closing properly. The caddy can then bow and jam inside the drive mechanism, which cannot eject it. Apple's repair for a jammed caddy was a complete replacement of the drive mechanism, because getting the caddy out means major disassembly that could not be done in the field.[5]
Care
[edit | edit source]- Wipe the caddy inside and out with a soft, lint-free cloth. Wipe discs in straight lines from the centre to the outside edge.[6][7]
- Never move or ship an AppleCD drive with a caddy inside it.[6][1]
- Do not let liquid or any foreign object get into the drive.[1]
Jammed or rejected caddies
[edit | edit source]Apple's owner's guide for the SC Plus gives this order when a caddy will not load or will not come out far enough:[1]
- Shut down the computer, leaving the drive on, and push the caddy gently into the drive.
- If that fails, switch the drive off and on again and press its eject button.
- If the caddy is still stuck, switch off both the computer and the drive. Straighten at least 3 inches (about 75 mm) of a large paper clip and push it firmly and exactly horizontally into the pinhole below and to the right of the drive door. Apple warns that doing this with the drive switched on can damage it.
- If the drive then fails to load the next caddy, shut everything down, wait about 15 seconds, switch on the drive and then the computer, and insert the caddy again.
A drive that will not accept a caddy at all, with a disc that is not dirty or damaged, points to the drive mechanism in Apple's service charts.[6] Apple's eject-button test also uses a caddy: switch the drive off and on, load any disc in a caddy, and press the eject button.[6]
