In computing and optical disc recording technologies, an optical disc (OD) is a flat, usually circular disc that encodes binary data in the form of pits and lands on a special material, often aluminum, on one of its flat surfaces. Its main uses are physical offline data distribution and long-term archival.Changes from pit to land or from land to pit correspond to a binary value of 1; …

optical storage, electronic storage medium that uses low-power laser beams to record and retrieve digital (binary) data. In optical-storage technology, a laser beam encodes digital data onto an optical, or laser, disk in the form of tiny pits arranged in a spiral track on the disk’s surface. A low-power laser scanner is used to “read” these pits, with variations in the intensity …
