Abstract
A disc tray for holding a disc on which an information signal is recorded and which can be loaded into a disc drive apparatus in a state where the disc tray holds the disc, the disc tray having an overall body formed into a thin plate-like shape and including a disc-receiving recess having an inner diameter larger than the diameter of a recording and/or reproducing disc and a depth larger than the thickness of the disc and arranged to removably hold the disc while having gaps in a direction in parallel with the surfaces of the disc and in a direction of the thickness of the disc, a bottom opening formed along the widthwise directional center of the disc tray in a range from substantially the central portion of the bottom portion of the disc-receiving recess to an end of the bottom portion and having a shape that the end of the bottom is opened, and a plurality of disc-separation-preventive portions formed to project into the disc-receiving recess from outside of the disc-receiving recess in such a manner that gaps at least permitting insertion of the disc are formed from the bottom portion of the disc-receiving recess.
