ABSTRACT:
A magnetic disk cartridge has a case, a magnetic disk rotatably housed in the case, a cleaning liner positioned between the magnetic disk and an inner wall surface of the case facing the magnetic disk and extending at least from an inner edge portion to an outer edge portion of the recording area of the magnetic disk, and a lifter positioned between the inner wall surface of the case and the liner. One end portion of the lifter is secured to the inner wall surface of the case, and the other end portion of the lifter is raised obliquely from the inner wall surface of the case to form a rising portion which pushes up the liner and makes the liner uniformly contact the magnetic disk over the area from the inner edge portion to the outer edge portion of the magnetic disk. The lifter is subjected to heat setting when the rising portion is formed.
