Abstract
PURPOSE: To optically reproduce a picture signal recorded on a recording disk at any speed with simple constitution by jumping a track nearly at a constant speed with tracking control placed in an open state.
CONSTITUTION: When switches 13 and 14 are opened by jumping commanding circuit 26, the tracking servo loop consisting of envelope detecting circuits 11a and 11b, compensating circuit 15, driving circuit 16, tracking element 17, rotary mirror 5, etc., is opened. Simultaneously, switch 22 is closed to control the jumping voltage generation section of the triangular wave of jumping voltage generating circuit 27 under the command of circuit 26 and the constant-speed rotation of mirror 5 is brought under control so that a fixed number of tracks recorded on the recording disk such as a disk will be jumped. Therefore, picture signals are optically reproduced at any speed, so that quick motion pictures, back motion pictures, etc., can be obtained in addition to slow motion pictures and still pictures.
