COMPACT DISK Meaning and
Definition
-
A compact disk, commonly known as a CD, is a small and portable optical storage medium used for digital data storage. It is a flat circular disc made of polycarbonate plastic with a diameter of 12 centimeters and a thickness of 1.2 millimeters. The CD is designed with a reflective metal layer, usually aluminum, and a protective layer to prevent scratches and damage.
CDs are widely used for storing and playing audio, video, and computer data files. They became popular in the 1980s as a replacement for vinyl records and cassette tapes due to their superior sound quality and durability. CDs utilize a standardized encoding technique known as PCM (Pulse Code Modulation), where analog audio signals are converted into digital data and engraved as tiny pits and lands on the surface of the disc.
To access the data stored on a CD, a CD player or CD-ROM drive is required. These devices use a laser beam that is directed onto the surface of the CD, which scans the pits and lands and converts them back into digital data. CDs can store up to 700 megabytes of data, allowing for the storage of multiple hours of audio or video content.
In addition to standard audio CDs, there are also various types of CDs, such as CD-R (Recordable), CD-RW (Rewritable), and CD-ROM (Read-Only Memory). These different formats allow for the recording and re-recording of data on rewritable discs or the pre-recording of data on read-only discs.
