Abstract
A disc of a magnetic disc cartridge is braked while the cartridge is outside of a receptacle of a magnetic disc memory unit by a radially extending leaf spring mounted on a wall of the cartridge so it has a free end engaging an aperture in a drive platter. The drive platter has an aperture that is engaged by a drive post of a drive disc connected to the memory drive shaft while the cartridge is inserted in the receptacle. The leaf spring is positioned so that the free end thereof is lifted out of the aperture by a post fixedly mounted on the memory unit to release the brake member while the cartridge is in place in the receptacle.
