optical storage
(Or "optical disc drive", "optical storage") A generic
term for any device that reads and/or writes optical media,
i.e. compact discs, DVDs and/or Blu-ray discs or future
media that uses light (from a small laser) to read data off a
removable, rotating disk.
At least one such drive is commonly installed in most {personal
computers} to allow them to play and/or record audio and video
media and load and store data such as program installers.
The floppy disk has been replaced by optical media due to its
vastly greater capacity, e.g. 50,000 megabytes for a dual-layer
blu-ray disc compared with 1.5 megabytes for a floppy (over
30,000 times as much).
