ABSTRACT:
In a recording medium playing apparatus, information on the medium (which is not reproduced when the medium is operated in a special playback mode) can not be arbitrarily reproduced when the medium is operated in an ordinary playback mode. A mask-clearing signal is stored in a memory at every unit information of reproduced one of all the information, the one being reproduced during the special playback mode in which the medium is operated when a predetermined data is processed. The apparatus judges whether the mask-clearing signal is stored in the memory at every unit information of the medium when the medium is operated in the ordinary playback mode, and unless the mask-clearing signal is stored, the unit information is inhibited from being output. In the ordinary playback mode, all of the information is not reproduced so as to retain the value and meaning of the game's software and become meaningless.
