The grasping member, disposed in the chassis, grasps a disc-like recording medium to be replayed among the plurality of recording mediums. The separation member separates one or more other disc-like recording mediums other than the recording medium to be replayed, from the recording medium to be replayed. The replay unit is in charge of replaying pieces of content information recording on an information-recorded surface of the disc-like recording medium to be replayed.

Abstract: A semiconductor memory device has a dynamic memory element constructed of a capacitor and a transistor; and a refresh timer circuit for automatically recharging the dynamic memory element at periodic time intervals corresponding to an electric charge holding time of the dynamic memory element which changes in accordance with an ambient temperature. Since the refresh timer circuit includes a current bias circuit for varying an electric current in accordance with the ambient temperature and an oscillation circuit for oscillating at a frequency corresponding to the electric current of the current bias circuit, the refresh cycle time changes in response to ambient temperature changes, thus reducing the requisite current capacity of the memory device power supply.
