Definition of optical disc: that is, high density optical disc (Compact Disc) is an optical storage medium (for example, magneto-optical disc is also an optical disc) which is different from fully magnetic carrier in modern times. It uses focused hydrogen ion laser beam to process the recording medium to store and reproduce information, also known as laser optical disc.
