Abstract: A disk changer for shortening the time required for the extraction of a disk from a magazine portion and the performance of the recording/reproducing operation is provided. First and second extracting members for extracting a disk from the magazine portion, and first and second deck members including recording and reproducing elements thereon, are simultaneously moved to the vicinity of a selected disk. Then, the disk is extracted from the magazine portion, and the recording/reproducing operation is carried out. The recording/reproducing operation can also be performed with respect to a disk from outside the disk changer via a tray member.
