る手段 とを具備したことを特徴とするＣＤプレーヤ。[Claims for Utility Model Registration] A pick-up that reads information signals recorded on each of two juxtaposed disks, a signal processing circuit that processes the information signals read by the pick-up, and a movement control. a pick-up moving means for moving the pick-up in the juxtaposed direction in response to a signal; an outermost circumferential position detecting means for detecting that the pick-up has been moved to the outermost circumferential position of each of the disks by the pick-up moving means; A control means is provided that provides a movement control signal to the pick-up moving means, and is also provided with an outermost circumference position detection signal from the outermost circumference position detection means and the information signal from the signal processing circuit, the control means comprising: In the initialization processing mode, a first movement control signal is sent to the pick-up moving means to move the pick-up toward the outermost circumference of one of the disks, and after reading the last track number on the one disk, the pick-up is moved to the other disk. means for respectively outputting a second movement control signal for moving each of the disks in the outermost circumferential direction; and when receiving the outermost circumferential position detection signal of each of the disks from the outermost circumferential position detecting means, the second movement control signal is transmitted through the signal processing circuit. A CD player comprising: means for storing at least the last song track number on each disk from the read information signal of the pickup given by the pickup; and means for outputting the last song track number information to a display section.
