In a magnetic disk cartridge having a liner (4) on the internal face (2a) of its cassette shell facing a magnetic disk, recesses (5) are formed, for example, radially in an area of the internal surface (2a) and the liner (4) is attached to at least the recesses (5). Therefore, the liner (4) attached to the internal face (2a) does not slack even when the environment changes and the liner (4) is always in contact with the magnetic disk with high precision.
