Detailed explanation-1: -A tiny laser within the hard drive temporarily spot-heats the area being written, so that it briefly reaches a temperature where the disk’s material temporarily loses much of its coercivity. Almost immediately, the magnetic head then writes data in a much smaller area than would otherwise be possible.
Detailed explanation-2: -An optical disk is an electronic data storage medium that can be written to and read from using a low-powered laser beam.
Detailed explanation-3: -A CD-ROM drive uses a low-power laser beam to read digitized (binary) data that has been encoded in the form of tiny pits on an optical disk.
Detailed explanation-4: -An optical drive is an internal or external computer disk drive that uses laser beam technology to read and write data. Optical disk drives are associated with compact discs, DVD and Blue-Ray technology.
