Although research into optical data storage has been ongoing for many decades, the first popular system was the Compact Disc, introduced in 1982, adapted from audio ( CD-DA) to data storage (the CD-ROM format) with the 1985 Yellow Book, and re-adapted as the first mass market optical storage medium with CD-R and CD-RW in 1988.

There are numerous formats of recordable optical direct to disk on the market, all of which are based on using a laser to change the reflectivity of the digital recording medium in order to duplicate the effects of the pits and lands created when a commercial optical disc is pressed. Emerging technologies such as holographic data storage and 3D optical data storage aim to …

The first attempts to record sound to an optical medium occurred around 1900. Prior to the use of recorded sound in film, theatres would have live orchestras present during silent films. The musicians would sit in the pit below the screen and would provide the background noise and set the mood for whatever was occurring in the movie. In 1906, Eugene Augustin Lauste applied for a patent to …

Optical sound is a means of storing sound recordings on transparent film. Originally developed for military purposes, the technology first saw widespread use in the 1920s as a sound-on-film format for motion pictures. Optical sound eventually superseded all other sound film technologies until the advent of digital sound became the standard in cinema projection booths. Optical …
- https://en.wikipedia.org/wiki/Optical_disc
In computing and optical disc recording technologies, an optical disc (OD) is a flat, usually circular disc that encodes binary data in the form of pits and lands on a special material, often aluminum, on one of its flat surfaces. Its main uses are physical offline data distribution and long-term archival.Changes from pit to land or from land to pit correspond to a binary value of 1; …

- https://en.wikipedia.org/wiki/Sound_recording_and_reproduction
The two main classes of sound recording technology are analog recording and digital recording . Sound recording is the transcription of visible vibrations in air onto a storage medium such as a phonograph disc. The process is reversed in sound reproduction, and the variations stored on the medium are transformed back into sound waves.
