Abstract
A time-axis correcting circuit for a recorded data reproducing device such as a video disc player in which, even when a dominant time-axis error component is not a single-frequency component, suppression thereof is sufficiently achieved with a relatively simple circuit configuration. The time-axis correcting circuit includes first and second time-axis correcting circuits, each of which has a flywheel oscillator servo loop. The oscillation frequency of the first flywheel oscillator servo loop is set close to the lowest frequency of the dominant time-axis error component to be suppressed while that of the second time-axis correcting circuit is set close to the highest frequency of the dominant time-axis error component to be suppressed.
