ABSTRACT:
A magnetic disk cartridge has a cassette shell formed of a pair of cassette shell halves encasing a rotatable magnetic disk supported by a center core, the inner surface of at least one cassette shell half lying parallel to the magnetic disk is formed with a recess which reduces the wall thickness of a portion of the cassette shell half, an elastic material is fixed on the cassette shell half to cover the recess, and a liner is attached to the surface of the elastic material facing the magnetic disk. The structure reduces the weight of the cassette shell and enhances its productivity and quality.
