Abstract
A multi-disc player testing apparatus for testing whether the multi-disc player satisfies the specific requirements is provided. The multi-disc player includes a carousel having multiple disc-accommodating areas and a disc-positioning sensor. The carousel defines a plurality of indicating slots for identifying each disc-accommodating area. The disc-positioning sensor scans the indicating slots to produce wave pulses in a form corresponding to the indicating slots. The multi-disc player includes a measuring module for receiving the wave pulses from the disc-positioning sensor, and measuring and comparing the number of the wave pulses and durations of each pulse with predetermined values to determine whether the multi-disc player satisfies the specific requirements.
