DVD (an abbreviation of "digital versatile disc" or "digital video disc") is a digital optical disc storage format invented and developed by Philips, Sony, Toshiba, and Panasonic in 1995.

The medium can store any kind of digital data and is widely used for software and other computer files as well as video programs watched using DVD players.

DVDs offer higher storage capacity than compact discs while having the same dimensions.

A gramophone record (phonograph record in the US), commonly known as a vinyl record or simply vinyl or record, is an analog sound storage medium in the form of a flat polyvinyl chloride (previously shellac) disc with an inscribed, modulated spiral groove.

The groove usually starts near the periphery and ends near the center of the disc.

The Compact Cassette or Musicassette (MC), also commonly called cassette tape, audio cassette, or simply tape or cassette, is an analog magnetic tape recording format for audio recording and playback.

It was released by Philips in 1962, having been developed in Hasselt, Belgium.

Compact cassettes come in two forms, either already containing content as a pre-recorded cassette, or as a fully recordable "blank" cassette.

It was designed originally for dictation machines, but improvements in fidelity led the Compact Cassette to supplant the Stereo 8-track cartridge and reel-to-reel tape recording in most non-professional applications.

Its uses ranged from portable audio to home recording to data storage for early microcomputers.

The first cassette player (although mono) designed for use in car dashes was introduced in 1968.

Between the early 1970s and the early 2000s, the cassette was one of the two most common formats for prerecorded music, first alongside the LP record and later the compact disc (CD).

Compact disc (CD) is a digital optical disc data storage format released in 1982 and co-developed by Philips and Sony.

The format was originally developed to store and play only sound recordings but was later adapted for storage of data (CD-ROM).

Several other formats were further derived from these, including write-once audio and data storage (CD-R), rewritable media (CD-RW), Video Compact Disc (VCD), Super Video Compact Disc (SVCD), Photo CD, PictureCD, CD-i, and Enhanced Music CD.

The first commercially available Audio CD player, the Sony CDP-101, was released October 1982 in Japan.

The LP (from "long playing" or "long play") is an analog sound storage medium, a vinyl record format characterized by a speed of rpm, a 12 or 10 inch (30 or 25 cm) diameter, and use of the "microgroove" groove specification.

Introduced by Columbia in 1948, it was soon adopted as a new standard by the entire record industry.

Apart from a few relatively minor refinements and the important later addition of stereophonic sound, it has remained the standard format for vinyl albums.
