In a disk reproducing apparatus a plurality of disks each carrying information recorded therein are inserted through an insertion opening and arrayed and held in a predetermined direction and a desired disk is selected for reproduction from the plurality of disks arrayed and held therein. The disk reproducing apparatus comprises a disk holding device including a plurality of trays arranged for holding thereon the plurality of disk respectively, a disk carrying device which carries the disk between the insertion opening and the tray, and a disk reproducing device which is carried to be positioned outside an area where a disk held by the disk reproducing device exists when the disk is not being reproduced and positioned that at least a portion is inside the area where the disk exists, when the disk is being reproduced. The disk carrying device and the disk reproducing device are juxtaposed in a direction in which disks are arrayed when the disk is not being reproduced. With this feature, minimization of the entire size of the apparatus and simplification of the construction are realized.
