Record Changers
A record changer or autochanger is a device that plays several phonograph records in sequence without user intervention. Record changers first appeared in the late 1920s, and were common until the 1980s. History The record changer with a stepped center spindle design was invented by Eric Waterworth of Hobart, Australia, in 1925. He and his father took it to Sydney, and arranged with a company called Home Recreations to fit it into its forthcoming phonograph, the Salonola. Although this novelty was demonstrated at the 1927 Sydney Royal Easter Show, Home Recreations went into liquidation and the Salonola was never marketed. In 1928, the Waterworths traveled to London, where they sold their patent to the new Symphony Gramophone and Radio Co. Ltd. Eric Waterworth built three prototypes of his invention, one of which was sold to Home Recreations as a model for its proposed Salonola record player as cited above, which is now reportedly in the collection of the Museum of Applied Arts & ...

Phonograph Record
A phonograph record (also known as a gramophone record, especially in British English), or simply a record, is an analog sound storage medium in the form 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. At first, the discs were commonly made from shellac, with earlier records having a fine abrasive filler mixed in. Starting in the 1940s polyvinyl chloride became common, hence the name vinyl. The phonograph record was the primary medium used for music reproduction throughout the 20th century. It had co-existed with the phonograph cylinder from the late 1880s and had effectively superseded it by around 1912. Records retained the largest market share even when new formats such as the compact cassette were mass-marketed. By the 1980s, digital media, in the form of the compact disc, had gained a larger market share, and the record left the mainstream in 1991. Since the 1990s, records ...

Cassette Tape
The Compact Cassette or Musicassette (MC), also commonly called the tape cassette, cassette tape, audio cassette, or simply tape or cassette, is an analog magnetic tape recording format for audio recording and playback. Invented by Lou Ottens and his team at the Dutch company Philips in 1963, Compact Cassettes come in two forms, either already containing content as a prerecorded cassette (''Musicassette''), or as a fully recordable "blank" cassette. Both forms have two sides and are reversible by the user. Although other tape cassette formats have also existed - for example the Microcassette - the generic term ''cassette tape'' is normally always used to refer to the Compact Cassette because of its ubiquity. Its uses have ranged from portable audio to home recording to data storage for early microcomputers; the Compact Cassette technology was originally designed for dictation machines, but improvements in fidelity led to it supplanting the stereo 8-track cartridge a ...

CD Changer
A CD player is an electronic device that plays audio compact discs, which are a digital optical disc data storage format. CD players were first sold to consumers in 1982. CDs typically contain recordings of audio material such as music or audiobooks. CD players may be part of home stereo systems, car audio systems, personal computers, or portable CD players such as CD boomboxes. Most CD players produce an output signal via a headphone jack or RCA jacks. To use a CD player in a home stereo system, the user connects an RCA cable from the RCA jacks to a hi-fi (or other amplifier) and loudspeakers for listening to music. To listen to music using a CD player with a headphone output jack, the user plugs headphones or earphones into the headphone jack. Modern units can play audio formats other than the original CD PCM audio coding, such as MP3, AAC and WMA. DJs playing dance music at clubs often use specialized players with an adjustable playback speed to alter the pitch ...

Original Cast Album
A cast recording is a recording of a stage musical that is intended to document the songs as they were performed in the show and experienced by the audience. An original cast recording or OCR, as the name implies, features the voices of the show's original cast. A cast recording featuring the first cast to perform a musical in a particular venue is known, for example, as an "original Broadway cast recording" (OBCR) or an "original London cast recording" (OLCR). Cast recordings are (usually) studio recordings rather than live recordings. The recorded song lyrics and orchestrations are nonetheless identical (or very similar) to those of the songs as performed in the theatre. Like any studio performance, the recording is an idealized rendering, more glossily perfect than any live performance could be, and without audible audience reaction. Nevertheless, the listener who has attended the live show expects it to be an accurate souvenir of the experience. History The British were t ...

Boxed Set
A box set or (its original name) boxed set is a set of items (for example, a compilation of books, musical recordings, films or television programs) traditionally packaged in a box and offered for sale as a single unit. Music Artists and bands with an extremely long and successful career often have anthology or "essential" collections of their boxes of music released as box sets. These often include rare and never-before-released tracks. Some box sets collect previously released boxes of singles or albums by a music artist, and often collect the complete discography of an artist such as Pink Floyd's '' Oh, by the Way'' and ''Discovery'' sets. Sometimes bands release expanded versions of their most successful albums such as Pink Floyd's ''Immersion'' box set versions of their ''The Dark Side of the Moon'' (1973), ''Wish You Were Here'' (1975) and ''The Wall'' (1979) albums. Pink Floyd have also released '' The Early Years 1965–1972'' box set which features mostly unreleased mat ...

Triple Albums
A double album (or double record) is an audio album that spans two units of the primary medium in which it is sold, typically either records or compact disc. A double album is usually, though not always, released as such because the recording is longer than the capacity of the medium. Recording artists often think of double albums as being a single piece artistically; however, there are exceptions such as John Lennon's '' Some Time in New York City'' (which consisted of one studio record and one live album packaged together) and OutKast's ''Speakerboxxx/The Love Below'' (effectively two solo albums, one by each member of the duo). Since the advent of the compact disc, albums are sometimes released with a bonus disc featuring additional material as a supplement to the main album, with live tracks, studio out-takes, cut songs, or older unreleased material. One innovation was the inclusion of a DVD of related material with a compact disc, such as video related to the album or DV ...
