ABSTRACT:
A disc cartridge capable for ensuring smooth movement of a disc receiver for a long period of time with high reliability. The disc cartridge includes a pivot pin on which a disc receiver is supported so as to be pivotally movable about the pivot pin and which is mounted on a lower inner surface of a casing to inwardly project therefrom. The pivot pin cooperates with a bearing mounted on an upper inner surface of the casing to constantly form a gap in a thickness direction of the casing in the casing which has a distance sufficient to ensure smooth pivotal movement of the disc receiver about the pivot pin in the casing.
