• Using rotary transformers, we developed a contactless power supply mechanism for a layer-selection-type recordable multi layer optical disk. This method provides stable resistance during disk rotation and requires minimum space for power supply mechanism. Our prototype transmits sufficient electrical power to change the optical reflectivity of the rotating disk. We studied the miniaturization of an optical drive and concluded that a slim-type drive is feasible with this contactless power supply mechanism.
