摘要
A method for time axis control for performing both coarse and fine time axis adjustment in accordance with relative speeds of a recording disk and a playback unit while the playback unit is recording or reproducing signals on or from the disk, wherein a color image is displayed during a scanning operation, which displayed image is natural in appearance. The pickup unit is first caused to follow a track formed on the recording medium in a tracking control operation. Repetitive track jumping operations are then effected over successive tracks by moving the pickup unit. For the track jumping operations, a time constant circuit within a circuit which performs the fine time axis adjustment is reset at least for the duration of each track jumping operation.
