Abstract
A disc playing and controlling apparatus which includes a plurality of magazine type disc players. When a first disc player is operating, the apparatus controls the other disk players to find and load a disc holding the next song to be played. Before searching for the next song, the controller determines whether one player is already set in a standby position or whether the next song is located in the player currently being operated. If no player has been set for the next program, the apparatus reads the next selection from a program list and identifies which magazine contains the selected program based on a data map. The map stores each player number and magazine number in an one-to-one relation with the table of contents data for each song.
