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.
Willard Boyle
In 1969, Boyle and George E. Smith invented the charge-coupled device (CCD), for which they have jointly received the Franklin Institute's Stuart Ballantine Medal in 1973, the 1974 IEEE Morris N. Liebmann Memorial Award, the 2006 Charles Stark Draper Prize, and the 2009 Nobel Prize in Physics. However, Eugene Gordon and Mike Tompsett, two now-retired colleagues from Bell labs, claim that its application to photography was not invented by Boyle. The CCD allowed NASA to send clear pictures to Earth back from space. It is also the technology that powers many digital cameras today. Smith said of their invention: "After making the first couple of imaging devices, we knew for certain that chemistry photography was dead."
