ABSTRACT:
A magnetic disc cartridge includes a cartridge shell and a magnetic disc which is formed integrally with a center core member and is supported for rotation in the shell. The shell is provided with a magnetic head window through which a magnetic head of a recording and reproducing system is given access to the magnetic disc and a spindle hole through which a spindle of the recording and reproducing system is engaged with the center core member to rotate the magnetic disc with the center core member. There is disposed between at least one side of the magnetic disc and the inner surface of the shell opposed to the side of the magnetic disc a wobbling suppressing plate which is in the form of a substantially circular flat plate and is movable in the direction of the axis of rotation of the magnetic disc at least at its outer peripheral portion.
