Before start of reproduction, it is determined if the disc loaded into the apparatus is a data disc on which information data such as letter or character data or picture data are recorded, or an audio disc on which audio signals are recorded, and the playback mode is automatically selected as a function of the type of the optical disc loaded into the apparatus. At the start time of the reproducing operation from the disc, the type discriminating data recorded on the disc are read out and, as a function of the contents of the type discriminating data, switching is made automatically between the data reproducing operation and the audio signal reproducing operation, while the type of the optical disc is displayed on the display section on the basis of the type discriminating data.
