Abstract

Consumer products based on new technologies are often introduced after a succesfull application of that technology in professional equipment.

Optical recording is an exception to this rule. Consumer applications of this technique as in the Laser-Vision video-disc and the Compact Disc digital audio systems are already for sale which cannot be said for the professional digital optical recorder (DOR) systems. This situation is partial due to different fields of interest, i.e. read-only (ROM) applications for the present consumer market and direct-read-after-write (DRAW) systems for professional use: a difference in media rather than in optical principles.
