ABSTRACT:
A disk cartridge includes a jacket body having upper and lower shells for receiving a magnetic disk medium therethrough. Upper and lower liners are adhered to inner surfaces of the upper and lower shells for removing fine dust attracted to upper and lower surfaces of the magnetic disk medium. In addition, upper and lower head windows are provided in the upper and lower shells, respectively, for permitting magnetic heads to access the magnetic disk medium when the magnetic disk medium is inserted through the upper and lower shells of the jacket body. A distance h.sub.1 is less than a distance h.sub.0, where h.sub.1 is the distance between said upper and said lower liners at a periphery of the upper and the lower head windows at least on an upstream side of the upper and the lower head windows with respect to a rotating direction of the magnetic disk medium, and h.sub.0 is the distance between the upper and the lower liners in a remaining area.
