ABSTRACT:
A rotary recording medium reproducing apparatus for reproducing a rotary recording medium in which an information signal consisting of a plurality of program contents and an address signal for discriminating a program number of the information signal are recorded, comprises a reproducing device for reproducing the information signal and the address signal from the rotary recording medium, a detection circuit for detecting the address signal from signals reproduced by the reproducing device, a setting circuit for setting a program number of a program which is to be reproduced after performing an automatic searching operation, a transferring device for transferring the reproducing means towards forward and backward directions on the rotary recording medium, and a comparator for comparing the program number set in the setting circuit with a program number of a program of the information signal being reproduced by the reproducing device, and producing and supplying a search signal to the transferring device so that the reproducing device is transferred towards a direction such that the two program numbers coincide. The comparator produces a signal to initiate reproduction of a predetermined mode from the beginning of the program whose program number is set in the setting circuit when the above two program numbers coincide with each other.
