Optical Storage Devices • An optical disk is a high-capacity storage medium. An optical drive uses reflected light to read data. • To store data‚ the disk’s metal surface is covered with tiny dents (pits) and flat spots (lands)‚ which cause light to be reflected differently. • When an optical drive shines light into a pit‚ the light cannot be reflected back. This represents a bit value of 0 (off). A land reflects light back to its source‚ Representing a bit value of 1 (on)

One who drives fast does not have proper and that well of a control
