===Audio recording===
Sony used the Compact Cassette format in many of its tape recorders and players, including the [[Walkman]], the world's first portable music player.<ref name=":5">{{Cite news |last=Haire |first=Meaghan |date=1 July 2009 |title=The Walkman |language=en-US |magazine=Time |url=http://content.time.com/time/nation/article/0,8599,1907884,00.html |access-date=17 January 2019 |issn=0040-781X |archive-date=2021-01-28  |archive-url=https://web.archive.org/web/20210128084123/http://content.time.com/time/nation/article/0,8599,1907884,00.html |url-status=live }}</ref> Sony introduced the [[MiniDisc]] format in 1992 as an alternative to [[Philips]] DCC or [[Digital Compact Cassette]] and as a successor to the Compact Cassette.<ref>{{Cite web |date=16 November 2013 |title=MiniDisc (1992–2013) |url=https://obsoletemedia.org/minidisc/ |access-date=17 January 2019 |website=Museum of Obsolete Media |language=en-GB |archive-date=2020-11-08  |archive-url=https://web.archive.org/web/20201108025210/https://obsoletemedia.org/minidisc/ |url-status=live }}</ref> Since the introduction of MiniDisc, Sony has attempted to promote its own audio compression technologies under the [[Adaptive Transform Acoustic Coding|ATRAC]] brand, against the more widely used MP3. Until late 2004, Sony's [[Walkman#Network Walkman|Network Walkman]] line of digital portable music players did not support the MP3 standard natively.

In 2004, Sony built upon the [[MiniDisc]] format by releasing [[HiMD|Hi-MD]]. Hi-MD allows the playback and recording of audio on newly introduced 1 GB Hi-MD discs in addition to playback and recording on regular MiniDiscs. In addition to saving audio on the discs, Hi-MD allows the storage of computer files such as documents, videos and photos.
