Method for playback of electronically recorded data

摘要

The method for replaying electronically stored data utilises a pulse emitted from a light source deflected by a moving mirror, and according to the angle of deviation strokes a predetermined beneath of a photosensitive material. The light impulse strikes a sick flank of a screw-shaped protuberances (1) on a rotating cylinder (2). After each reflection of a pulse a new section of the photosensitive surface is brought into the beam path.
