Abstract

The disc player accommodates a plurality of CD-I discs, to each of which program data required to reproduce information on the disc is recorded at a predetermined area thereof. The disc player has a disc changer to selectively supply each CD-I disc to a reproducing unit. The method of reproducing information of the disc player includes the steps of: reading the program data from the CD-I disc, and writing the read program data into a memory, with respect to all of the CD-I discs accommodated in the disc changer; and performing a reproduction operation with reference to the program data written in the memory at the time of the reproduction operation of the information on the CD-I disc.
