Caddy (hardware)

（重定向自HDD caddy）

A CD caddy being inserted into a Macintosh Centris 660AV

In computer hardware, a caddy refers to a container used to hold some media, such as a CD-ROM. If the medium is a hard disk drive, the caddy is also referred to as a disk enclosure. Their functionality is similar to that of the 3.5" floppy disk.

The purpose of a disk caddy is to protect the disk from damage when handling; their use dates back to at least the Capacitance Electronic Disc in 1976, and they were used in initial versions of Blu-ray Discs, though as a cost-saving measure newer versions use hard-coating technology to prevent scratches and do not need a caddy.
