Definitions
- holographic data storage which involves applying the items of information three-dimensionally in the optical data storage medium.
- a position regulating system for controlling the write and read head in its position with respect to the optical storage medium, use is made of a position regulating system in which, by means of a beam reflected in the storage medium, the focus and track control is performed by means of a detector.
