Optical Drive

What are they? What does they do? Lets find out.

What is an optical drive?

In computing, an is a optical disk drive (ODD) is a disk drive that uses laser light or electromagnetic waves within or near the visible light spectrum as part of the process of reading or writing data to or from optical disks. Optical disc drives are an integral part of stand-alone consumer appliances such as CD players, DVD players and DVD recorders. They are also very commonly used in computers to read software and consumer media distributed on disc, and to record discs for archival and data exchange purposes.

How do they work?

Optical discs are used to back up relatively small volumes of data, but backing up of entire hard drives, as of 2011 typically containing many hundreds of gigabytes, is less practical than with the smaller capacities available previously. Large backups are often made on external hard drives, as their price has dropped to a level making this viable; in professional environments magnetic tape drives are also used.
