Information recorded on a non-CAV type recording disk is detected by a pickup device having an information reading point repeatedly moved during spaced intervals in a radial direction across recording tracks on the disk in response to a special playback operation command. Predetermined portions of the information so picked up, during periods between track jump operations, are entered into a memory device and the stored information read out therefrom to provide playback information for the special playback operation. The information reading point is moved by the track jump operations to positions establishing a time period sufficient to enable stabilization of a time base error in the information, caused by said track jump operations, before entry of the information into the memory is begun.
