Optical storage refers to a class of data storage systems that use light to read or write data to an underlying optical media. Although a number of optical formats have been used over time, the most common examples are optical disks like the compact disc (CD) and DVD.
Optical discs are not prone to uncontrollable catastrophic failures such as head crashes, power surges, or exposure to water like hard disk drives and flash storage, since optical drives' storage controllers are not tied to optical discs themselves like with hard disk drives and flash memory controllers, and a disc is usually recoverable from a ...
Optical drives for computers come in two main form factors: half-height (also known as desktop drive) and slim type (used in laptop computers and compact desktop computers). They exist as both internal and external variants. Half-height optical drives are around 4 centimetres tall, while slim type optical drives are around 1 cm tall.

5D optical data storage (also branded as Superman memory crystal, [1] a reference to the Kryptonian memory crystals from the Superman franchise) is an experimental nanostructured glass for permanently recording digital data using a femtosecond laser writing process. [2]
In the history of optical storage media there have been and there are different optical disc formats with different data writing/reading speeds. Original CD-ROM drives could read data at about 150 kB/s, 1× constant angular velocity (CAV), [1] the same speed of compact disc players without buffering.
A magneto-optical drive is a kind of optical disc drive capable of writing and rewriting data upon a magneto-optical disc. 130 mm (5.25 in) and 90 mm (3.5 in) discs are the most common sizes. In 1983, just a year after the introduction of the compact disc , Kees Schouhamer Immink and Joseph Braat presented the first experiments with erasable ...
The following are examples of optical storage media excluded from this article: Holographic data storage - either still in development, or available but generally only encountered in niche usage as of 2007. Laserdisc - not used for recordable data storage in the computing world, although recordable formats did exist briefly.
