Abstract
Table of contents (TOC) information is read before a plurality of recording mediums, such as compact disks, each having recorded information to be reproduced and TOC information, with respect to the recorded information are played back. Playback operation of the recording mediums is controlled based on the read TOC information. Programmed information which indicates a sequence according to which the recorded information of the recorded mediums is to be reproduced is read from a programmed information memory based on the result of checking of the recording mediums. The playback operation of the recording medium is controlled by a playback control unit based on the programmed information thus read. The playback operation can immediately be controlled based on the stored programmed information. If there is new programmed information relative to the recording mediums, the playback operation of the recording mediums can be controlled according to the new programmed information by employing only the stored TOC information. Therefore, even when new programmed information is established, the playback operation can quickly be controlled.
