ABSTRACT:
In a check mode, a determination is made as to whether or not a disc is stored in each of disc storage positions, and mapping data representing the presence of the discs are recorded into a memory. Disc storage and removal operations are performed based on such mapping data. Further, in a disc storage mode, when a disc is already stored in a specific storage position, the word "FULL" is displayed. When no disc is stored in a specific storage position, the word "EMPTY" is displayed. Further, in a skip button disc storage mode, one of empty disc storage position number is displayed, and when the skip button is pushed, the next empty disc position number is displayed. When the enter button is pushed while an empty disc storage number is displayed, a disc is stored into the empty disc storage position represented by the displayed number. Moreover, in the check mode, when power is turned off, the check mode is continued in order to complete the mapping process.
