Compact disc
Compact disc (CD) is a digital optical disc data storage format that was co-developed by Philips and Sony and released in 1982. The format was originally developed to store and play only sound recordings (CD-DA) 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.
Technological and industrial history of 20th-century Canada
The compact disc (CD) and the digital video disc (DVD) were introduced at this time. The CD, which appeared in 1982, became a favourite format for musical recordings. By 1986 most music stores in Canada had phased out the LP and replaced it with the CD. It was also used for other purposes including data storage in the form of the CD-ROM. A closely related format, the DVD, with greater storage capacity than the CD, was introduced in 1997. In 1986, Americ Disc of Drummondville, Quebec began to manufacture CDs and after 1997, DVDs and has become one of the largest suppliers of this product in North America. The infrared-based TV remote control became popular with Canadians in the early 1980s.
