Long playing (LP), either 10 or 12- for Recorded Music for about 30 Year s, from the late 1950s until CD s effectively replaced them in the late 1980s . The primary competing format at this time was the Audio Cassette , which was gradually replacing the Reel-to-reel Tape . Music industry pundits and Audiophiles of the era argued both for and against the audio quality of each format, some aspects of which are discussed below. Both formats were Analog , as Digital music recording was not technically feasible on any significant scale. PHYSICAL ASPECTS Between 1948 and 1955, the majority of LPs were 25 cm (10") in diameter, matching that of 78 rpm singles. Eventually the diameter was increased to 30 cm (12") (matching higher-priced classical 78s), and 10" records were relegated to the status of EPs ( Extended Play ). At first, LPs played for approximately 45 minutes maximum, divided over two sides. (LPs generally provided 30 minutes of programming.) However, in 1952, Columbia Records began to bring out LPs that played for as long as 52 minutes, or 26 minutes per side. These were used mainly for the original Cast Albums of some Broadway musicals, such as '' Kiss Me, Kate '' and '' My Fair Lady '', or in order to fit an entire play, such as the 1950 production of '' Don Juan In Hell '', onto just two LPs. But the 52-minute playing time, even for an LP, was rare, and most LPs continued to be issued with a 30- to 45-minute playing time, even as late as 1980. This play time was a significant improvement on that of the previous dominant formats, the , but this could prevent correct ordering of sides of each album in question, unless two sets were used, or if a multiple-record set were released in "automatic sequence". This was an established practice for 78rpm albums. In that format, a four-disk set would have Side 8 opposite Side 1, Side 7 opposite Side 2, Side 6 opposite Side 3, and Side 5 opposite Side 4, so that the first four sides would play without the listener's intervention, though not without interruption as the changer lifted and cleared the pickup arm, dropped the next disk onto the constantly spinning turntable, and the pickup arm was lowered to the beginning of it. Having an so that only a fraction of its actual weight was holding it down. The large s Suspended in the air, as well as any similar substances which might be spilled onto the record, and therefore a ritual usually reserved for the owner of the record was to clean the record carefully using an appropriate Record Cleaner and optionally some Antistatic Record Cleaning Fluid . {Link without Title} Brittle, as well as , people were less inclined to lug the significant weight of a "stack" of records around with them, for example when visiting friends or when travelling, than a similar quantity of music compiled onto 90-minute Cassette Compilation-tape s—or in comparison with today's digital formats. So-called record . The term DJ has since come to encompass also those with a specialist-level of skill in mixing Dance Music and perhaps even Rap ping or playing Musical Instrument s, but the original DJ's task was relatively passive: simply to mix each track through to the subsequent one between songs, and perhaps make occasional announcements and chat with patrons in order to take requests in between, while songs were actually playing. TECHNICAL ASPECTS The audio quality of LPs increased drastically over time and nearly rivals some of the more modern distribution methods, although some purists prefer the sound of LPs. Many early LP records were mono ( Monaural ), but Stereo LP records were available at least by the end of the '50s . {Link without Title} Later again, Quadraphonic, or 4-channel records became available. These were not very popular, probably because of the lack of 4-channel record players. SEE ALSO |
