Claims

[Scope of utility model registration request]

(1) A planar magnetic disk is rotatably housed in a case constructed by combining a pair of case members, and an outer circumferential bracket that abuts each other on opposing surfaces of the pair of case members. and a magnetic disk cartridge including a rib surrounding the magnetic disk rotation area and an opening that opens to the outside in a part of the outer circumferential rib, wherein the rib surrounding the magnetic disk rotation area corresponds to the opening. A magnetic disk rotation area is formed in a continuous manner at the same height as the outer circumferential ring in a portion where the magnetic disk rotates from the opening, and a stepped shape is formed in other portions to engage with each other between the pair of case members. A magnetic disk cartridge characterized by:

(2) A magnetic head insertion window is provided in the magnetic disk rotation area of the pair of case members, a shutter for opening and closing the magnetic head insertion window is attached to the case, and a shutter is provided in the case at least one corner of the pair of case members. , a shutter biasing spring insertion portion formed by the two ribs is provided, and the spring insertion portion is passed through an opening formed by cutting out a part of the outer peripheral rib to the outside, and the magnetic disk rotation area is A registered utility model characterized in that the surrounding rib is continuous at the same height as the outer circumferential rib at a portion corresponding to the spring insertion portion, and is formed so as to partition a magnetic disk rotation area from the spring insertion portion. A magnetic disk cartridge according to claim 1.
