is a medium for storing sound and music. The term is applied to both the physical recording media and the recording formats of the audio content- in computer science it is often limited to the audio file format, but its wider use usually refers to the physical method used to store data.

also known as Digital Video Disc or Digital Versatile Disc, is an optical disc storage media format. Its main uses are video and data storage. DVDs are of the same dimensions as compact discs (CDs), but are capable of storing just under seven times as much data.
is an audio Compact Disc that contains music in surround sound format. unlike Super Audio CD and DVD-Audio, which require a specialized player, a DTS-CD is compatible with most standard CD and DVD players with a digital output.
eventually came out with it was WAVE form (WAV), dolby digital surround cinema sound, digital theatre system (DTS), sony dynamic digital sound (SDDS), and mp3. DCC was envisaged as a cheaper alternative to DAT. DCC shared the same form factor as analog cassettes, and DCC recorders could play back either type of cassette. This backward compatibility allowed users to adopt digital recording without rendering their existing tape collections obsolete.
is a magneto-optical disc-based data storage device initially intended for storage of up to 80 minutes of digitized audio
was a signal recording and playback medium. DAT has the ability to record at higher, equal or lower sampling rates than a CD
is a patented encode-decode process, now owned by Microsoft, that improves the audio quality of standard Redbook audio CDs, while retaining backward compatibility with existing Compact disc players.
came with PCM, audio interchange file format (AIFF), and sound designer (by digidesigner) and is an optical disc used to store digital data. It was originally developed to store sound recordings exclusively, but later it also allowed the preservation of other types of data.
is a home video disc format, and was the first commercial optical disc storage medium.
its similar to a standard cassette, but twice the size and speed. The Elcaset also had all the features of deluxe open reel decks, like separate heads for erase, recording, and playback, remote control, and heavy duty transports for low wow & flutter and excellent specs.
The first half-inch, analog videocassette recorder (VCR) format. The first Betamax cassettes held only one hour of video, but the capacity was subsequently increased to hold an entire movie.
Quadraphonic audio was one of the earliest consumer offerings in surround sound. It was a commercial failure due to many technical problems, which were solved too late to save the technology from disaster.
is now called 4.0 surround sound – uses four channels in which speakers are positioned at the four corners of the listening space, reproducing signals that are (wholly or in part) independent of one another.
is an audio storage medium introduced by Olympus. It uses the same width of magnetic tape as the Compact Cassette but in a much smaller container. By using thinner tape and half or a quarter the tape speed, microcassettes can offer comparable recording time to the compact cassette.
is a tape cassette format introduced by Philips. It is used primarily in dictation machines and was also employed as a data storage for the Philips P2000 home computer. the Mini-Cassette does not use a capstan drive system; instead, the tape is propelled past the tape head by the reels. This is mechanically simple and allows the cassette to be made smaller, but produces a system unsuited to any task other than voice recording.
Stereo 8 was created by a consortium led by Bill Lear of Lear Jet Corporation, along with Ampex, Ford Motor Company, General Motors, Motorola and RCA Victor Records (RCA). It was a further development of the similar Stereo-Pak four-track cartridge.
is a magnetic tape sound recording format. Its uses ranged from portable audio to home recording to data storage for early microcomputers.
is a magnetic tape sound recording cartridge technology. The in-car tape player that played the Stereo-Pak cartridges was called the Autostereo, but it was generally marketed under the common Stereo-Pak trade name.
commonly called stereo, is the reproduction of sound using two or more independent audio channels through a symmetrical configuration of loudspeakers in such a way as to create the impression of sound heard from various directions, as in natural hearing.
is a way to record music (or other sounds) that was popular during most of the twentieth century. Vinyl records are played on a phonograph. A vinyl record is a disk made of vinyl plastic. The sound is recorded on a very fine line or groove which goes around and around in a spiral from the outside edge of the disk to the center. The phonograph plays the sound with a needle that touches the groove.
is the form of magnetic tape audio recording in which the recording medium is held on a reel, rather than being securely contained within a cassette.
the process of recording electrical impulses that represent sound waves and using them for broadcast.
is a type of analog audio storage in which the recording is made onto thin steel or stainless steel wire.
is an analog sound storage medium consisting of a flat disc with an inscribed, modulated spiral groove. The groove usually starts near the periphery and ends near the center of the disc.
is a storage medium used to operate a mechanical organ, electronic carillon or orchestrion. Originally made of paper, modern rolls are made of thin plastic. The mechanism of the instrument reads these as the roll unwinds, using a pneumatic sensing device called a tracker bar, and the mechanism subsequently plays the instrument.
were the earliest commercial medium for recording and reproducing sound. Commonly known simply as "records" in their era. these cylinder shaped objects had an audio recording engraved on the outside surface which could be reproduced when the cylinder was played on a mechanical phonograph.
