Substrate, oxide layer, coating layer, detail, laser beam, optical head, linear encoder, detector, laser diode, linear motor, and a disk—these are the parts of the so-called optical disk information storage system.
This system’s purpose is to copy solid state burned up data to the disk for storage purposes. The laser is used to read and interpret the data. A mirrored laser beam is transformed to electric waves and the said waves replicate the original data. The linear encoder and the motor inside make recovery and copying of files possible. Optical disk is indeed a new wave of technological advancement.
