☯ Optical Media :

↪ Optical media are storage media that hold content in digital form and that are written and read by a laser; these media include all the various CD and DVD variations, as well as optical jukeboxes and autochangers.

↪ Optical media have a number of advantages over magnetic media such as the floppy disk.

↪ Optical disk capacity ranges up to 6 gigabytes; that's 6 billion bytes compared to the 1.44 megabytes (MB) - 1,440,000 bytes - of the floppy.

↪ One optical disk holds about the equivalent of 500 floppies worth of data.

↪ Durability is another feature of optical media; they last up to seven times as long as traditional storage media.
