A disc tray includes a bottom wall including an outer periphery and an inner rib supporter supporting the lowermost disc from below. The bottom wall is thickened from the outer periphery toward the inner rib supporter. The lowermost disc includes a data recording area, an inner rib, and an outer rib. When the lowermost disc is stationary, the outer rib of the lowermost disc and the upper surface of the bottom wall are separated by a gap. When the lowermost disc is inclined in such a manner that part of the outer rib of the lowermost disc comes into contact with the upper surface of the bottom wall, the data recording area of the lowermost disc and the upper surface of the bottom wall are separated by a gap greater than thickness of the outer or inner rib.
A disc tray for storing a plurality of discs stacked together, the disc tray comprising a bottom wall including an outer periphery and an inner rib supporter, the bottom wall being thickened from the outer periphery toward the inner rib supporter in a cross section along thickness of the disc tray, the inner rib supporter supporting a lowermost disc of the plurality of discs from below, the lowermost disc including a data recording area, an inner rib, and an outer rib,
