ABSTRACT:
Rotation of a tray roulette for use in a disk changer is controlled by using disk ID codes, a start code and an end code, each code being produced while a scanner electrode contacts ID electrodes, start electrodes and end electrodes as the tray roulette rotates; specifically, the method generates fixed voltages while the scanner electrode contacts the ID electrodes, the start electrodes and the end electrodes; produces the ID codes, the start code and the end code by converting the fixed voltages received from the ID electrodes, the start electrodes and the end electrodes; and controls the rotation of the tray roulette by using the ID codes in order to rotate and stop the tray roulette at a pickup position.
