The CD full form is Compact Disc. A CD, or Compact Disc, is a digital optical disc storage format used to store and playback various types of data, including audio, video, and computer files. It was introduced in the early 1980s and quickly became the standard medium for distributing music albums.
CDs are typically circular in shape, with a diameter of 12 centimetres (4.7 inches), and they are made of a polycarbonate plastic substrate with a reflective metallic layer and a protective coating. Information is stored on the disc in the form of small pits and lands on the reflective layer, which is read by a laser beam in CD players or CD-ROM drives.
Types of CD
There are several types of CDs that serve different purposes. Here are some common types:
- CD-Audio: This is the standard type of CD used for audio recordings. It can store up to 74 minutes of high-quality audio.
- CD-ROM: CD-ROM stands for Compact Disc Read-Only Memory. These CDs contain data that can only be read and not written or modified. CD-ROMs are commonly used for software, games, and multimedia applications.
- CD-R: CD-R stands for Compact Disc Recordable. These discs allow users to write data onto them once. Once data is recorded on a CD-R, it cannot be erased or modified.
- CD-RW: CD-RW stands for Compact Disc Rewritable. These discs are similar to CD-Rs but can be erased and rewritten multiple times. CD-RW discs are useful for data backup and temporary storage.
- CD+R and CD+RW: These are enhanced versions of CD-R and CD-RW discs that provide additional features such as improved compatibility with certain audio players and extra storage capacity.
- CD-Video: CD-Video is a format that combines audio and video content on a single disc. It was primarily used for storing music videos and movies but has been largely replaced by other formats like DVDs and Blu-ray.
- CD-MP3: CD-MP3 refers to CDs that are encoded with compressed MP3 audio files. These discs can store a large number of songs in a compressed format, allowing for longer playtimes.
- CD-Extra: Also known as Enhanced CD, CD-Extra combines audio tracks with additional multimedia content like videos or computer files. This format is commonly used for music albums with bonus material.
