Summary:PROBLEM TO BE SOLVED: To provide a disk tray capable of contributing thinning of a magazine while suppressing disk distortion.SOLUTION: A bottom wall of a disk tray is provided with an inner peripheral rib support part supporting an inner peripheral rib of a lowest disk from below. A thickness of the bottom wall of the disk tray is formed so as to become thicker from an outer peripheral part toward the inner peripheral rib support part. In a static state, a space is formed between an outer peripheral rib of the lowest disk and an upper surface of the bottom wall of the disk tray. In a state where the lowest disk is inclined so that a part of the outer peripheral rib of the lowest disk contacts the upper surface of the bottom wall of the disk tray, a space lager than the thickness of the outer peripheral rib or inner peripheral rib is formed between a data recording area of the lowest disk and the upper surface of the bottom wall of the disk tray.SELECTED DRAWING: Figure 7 【課題】ディスクに歪みが生じることを抑えつつ、マガジンの薄型化に寄与することができるディスクトレイを提供する。【解決手段】ディスクトレイの底壁に、最下位のディスクの内周リブを下方から支持する内周リブ支持部を設ける。ディスクトレイの底壁の厚さは、外周部から内周リブ支持部に近づくに従って厚くなるように形成する。静止状態において、最下位のディスクの外周リブとディスクトレイの底壁の上面との間には隙間を形成する。最下位のディスクの外周リブの一部がディスクトレイの底壁の上面に接触するように最下位のディスクが傾斜した状態において、最下位のディスクのデータ記録領域とディスクトレイの底壁の上面との間には、外周リブ又は内周リブの厚さよりも大きい隙間を形成する。【選択図】図7
