ABSTRACT:
An adapter which enables a smaller size magnetic disc cartridge to be driven by a disc drive system for a larger size magnetic disc cartridge has an adapter body which is substantially the same as the casing of the larger size magnetic disc cartridge in the outer dimensions and contour. A disc holding portion in which the smaller size magnetic disc cartridge can be removably set is formed in the adapter body. A first opening is formed in the adapter body in a position substantially corresponding to the position of the center core hole in the casing of the larger size magnetic disc cartridge, and a second opening is formed in the adapter body in a position substantially corresponding to the position of the magnetic head insertion window in the casing of the larger size magnetic disc cartridge. The smaller size magnetic disc cartridge is set in the disc holding portion so that its center core hole and magnetic head insertion window are respectively aligned with the first and second openings of the adapter body and the distance between the recording surface of the magnetic disc medium thereof and a reference surface of the adapter body is substantially equal to the distance between the recording surface of the magnetic disc medium of the larger size magnetic disc cartridge and a surface of the casing of the larger size magnetic disc cartridge corresponding to the reference surface of the adapter body.
