Compact Disc (CD)

Technology / Home Audio / Compact Disc (CD): The most popular format for conveying music and data currently available. It is among the first digital media to take over from the analog formats of phonograph records and tapes; coming to the market in the early 1980's. Developed by Phillips, Sony, and Pioneer, it records information on the now familiar shiny discs by deforming the inner metal foil on the disc with tiny micro pits burned in by a laser. These pits taken together, form a binary digital code, which when converted to bits, then bytes, can recreate the original information, such as audio. It's superiority as a format, consists of the fact that the process gets around such problems as: noise, hiss, pops, transducer irregularities, and other audible problems that made analog carriers a less than fully high fidelity mode. Dynamic range exceeds 100 decibels, a sufficient soft/loud difference to make the reproduction very lifelike. Frequency response is at the theoretical limits of human hearing and unwanted aural artifacts are generally below the threshold of perception. The only significant improvement is the DVD borne addition of multiple channels, to recreate the original sonic environment. In short, it's the best thing to come along since Mozart sat down at the piano.
