Abstract
An electrical device allows voltage to be supplied with minimal power loss. The electrical device has elements with differing supply voltage demands. The same supply voltage is supplied in each case to the elements. The supply voltage can be switched over. The supply voltage is set as a function of the currently highest voltage demand of the elements. The electrical device can be configured as a playback device for optical memory disks, and can include a device for driving an optical memory disk inserted into the playback device and for positioning a scanning unit.
