Method and apparatus for time axis control.

摘要

57 A method for time axis control in which both coarse and fine time axis adjustment are performed in accordance with the relative speeds of a recording disk (1) and a playback unit during recording or reproduction in which repetitive track jumping operations are effected over successive tracks by moving the pickup unit. During the track jumping operations, a time constant circuit (R1, C2) within a circuit (9) which performs the fine time axis adjustment is reset during each track jumping operation. This enables a colour image to be displayed during a scanning operation which is natural in appearance by preventing a build-up of time axis errors caused by the track jumping operation.
