Optical storage

From The IT Law Wiki

Optical storage refers to data storage on an optically readable medium. Data is recorded by making marks in a pattern that can be read back with the aid of light. A common technique used by computers involves a tiny beam of laser light precisely focused on a spinning disc. There are other means of optically storing data and new methods are in development. Optical storage differs from other data storage techniques that make use of technologies such as magnetism or semiconductors.
