COMPACT DISKS Meaning and
Definition
-
Compact disks, often referred to as CDs, are optical storage media used for recording, storing, and playing various forms of digital data. They are widely recognized for their round, flat shape, typically measuring about 12 centimeters in diameter, with a small central hole. CDs consist of a polycarbonate layer, which is the main body of the disk, and a reflective metal layer, usually aluminum, covered by a protective layer.
These disks store data in a highly compressed digital format by using microscopic pits and lands on the polycarbonate surface. A laser beam reads this data by scanning the surface, detecting the varying reflections caused by the pits and lands. The reflective layer ensures that the laser beam is effectively reflected onto a photosensitive detector.
Introduced in the early 1980s, CDs revolutionized the way audio, video, and software data are distributed and played. They offer a significantly higher storage capacity compared to audio cassettes or early magnetic storage devices. Originally designed for audio recordings, CDs quickly expanded to include various multimedia applications, such as video games, movies, and software installation. They gained immense popularity due to their durability, ease of use, and high-quality audio and video playback.
With the advancement of technology, CDs have been largely replaced by newer digital media formats, such as digital downloads and streaming services. However, they continue to be used for archival purposes, as well as by some audiophiles who prefer the superior sound quality offered by CDs over digital reproduction.

Etymology of COMPACT DISKS
The word "Compact Disc" (CD) is derived from a combination of two different words.
1. Compact: It comes from the Latin word "compactus", which means "compressed" or "pressed together". In this context, it refers to the smaller size and compressed data storage of a CD compared to older audio formats like vinyl records or cassette tapes.
2. Disc: It comes from the Latin word "discus", which means a "flat, circular object". This term is used to describe the shape of the optical storage medium on which the audio, video, or data is stored.
Hence, the term "Compact Disc" (CD) suggests a technology that has compressed audio/data stored on a small, flat, and circular medium.
