Big Disk

A typical CD has a diameter of only 12 cm and about 80 minutes of audio data can be stored on it. Smaller CDs are also manufactured for storing single songs (called CD singles). They are 8 cm in diameter and can store 24 minutes of audio.

The major research and development was done by Phillips and Sony. One of the first CD came way back from the market of 1982 and to this day, remains one of the most popular recordings.

In 1979, Phillips and Sony started a joint working group to design a successful digital audio discs. After a year `s work and many experiments and discussions, the compact disc was invented. No person can only be said to have invented, a large group collectively invented the compact disc.

In August 1982 the first CD for commercial was manufactured in a factory in Germany Phillips. The first music title that was released on a CD was "The Visitors (1981) by ABBA. Shortly thereafter, in October the same year, Sony CD players also reached the markets. The event is often cited as "Big Bang" in the field of digital audio.

The new concept was an immediate success in the marketplace. Consumers were excited by the quality of the audio CD. The price of CD players sank rapidly, as a result, the popularity increased even more.

A compact disc is a disc of 1.2 mm thick polycarbonate plastic that weighs about 16 grams. To make the surface reflective a very thin layer of aluminum is applied on one side of the disc. A film of varnish is also applied to act as a protective shield. The label is printed on the other side using normal printing methods like offset printing or screen. Data are stored on a CD as an array of tiny indentation called pits that are encoded in a spiral track. A pit is 500 nm wide and 100 nm deep and the length varies from 850 to 3500 nm. Areas between two pits are called lands.

CDs are more durable than storage formats Audio valuable. However, they can be damaged some environmental factors and daily use. The data are much closer of the label, so more damage occurs if scratches are made on the label. The logical format for storing audio data on a CD is a 2-channel 16-bit PCM encoded data at a sampling frequency rate of 44.1 KHz. The sampling rate was chosen as a direct result of sampling rate theorem of double frequency needed in the records. With some more calculations, the exact sampling rate of 44.1 KHz was decided.

The CDs are available in a number of different variations. Some of them are:

CD Text - Compact Disc that allows the storage of information such as song name, artist, album name as text data with standard audio CD.

CD Graphics - These contain additional graphics data on the CD. They normally operate on a normal CD, but can output graphics data when playing on a CD + G.

CD - ROM or Read Only Memory, as its name suggests are CDs from which data can be read.

Video CD - Video CDs or VCDs are CDs of video data.

Photo CD - it was designed by Kodak for storing digital photos in a Compact Disc. They were able to store over 100 pictures when launched.

CD + RW - they are CDs on which data can be written erase and re-written more than once.
