ABSTRACT:
A CD-ROM disc reproducing apparatus of the present invention includes a memory for storing progression data of a program that plays and controls a CD-ROM disc, a power supply switch and a book marker switch. The memory sequentially stores therein progression data of the program. When the playback control of the CD-ROM disc is directly stopped by the power supply switch, the contents of the memory are not saved. However, when the playback control of the CD-ROM disc is stopped by the book marker switch or when the playback control of the CD-ROM disc is interrupted unintentionally, the progression data of the program are saved by the memory. Then, when the playback control of the CD-ROM disc is resumed, the content stored in the memory is accessed and the playback control state of the CD-ROM disc can be recovered to the state presented at a timing point that the playback control state of the CD-ROM disc is interrupted. Thus, even if the power switch is turned off by a particular key because of an urgent business or even if the power switch is turned off by force when the door is unintentionally opened, when the playback is resumed, the playback of the CD-ROM disc is resumed from the operation state presented at a timing point in which the playback is interrupted.
