Abstract
In a magnetic disk cartridge, a magnetic disk sheet is accommodated in a casing in such a way that it may be rotated. A heat-sensitive adhesive is provided on one side of a raw sheet material composed of the same material as wear-resistant members which are to be bonded to the casing. The raw sheet material is cut into wear-resistant members and each of the wear-resistant members is heated in order to melt the heat-sensitive adhesive while the wear-resistant member is supported with a suction force. Then the wear-resistant member is released while the heat-sensitive adhesive is in a molten state, and it is pressed against the central portion of the inner surface of the casing. Thus the casing has a wear-resistant member bonded to a central portion of the inner surface of the casing.
