Detailed explanation-1: -A hard plastic substrate forms the base, and then a reflective layer–typically aluminum foil for mass-produced disks–is used to encode the digital data. Next, a layer of clear polycarbonate protects the foil and allows the laser beam to pass through to the reflective layer.
Detailed explanation-2: -An optical disk is any computer disk that uses optical storage techniques and technology to read and write data. It is a computer storage disk that stores data digitally and uses laser beams (transmitted from a laser head mounted on an optical disk drive) to read and write data.
Detailed explanation-3: -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.
