ッジ。The disk case 1 includes a drive shaft insertion window 3 and a magnetic head insertion window 4, and a disk 2 rotatably installed in the disk case 1. The disk 2 includes a disk-shaped sheet 9 and a central portion of the sheet 9. The hub 10 is integrally connected to the drive shaft insertion window 3 and has a spindle insertion hole 15 in the center of the hub 10 into which a spindle 21 on the magnetic recording device side is inserted. Two fixed inner contacts P2 inscribed in the circular outer peripheral surface of the shaft 21. P3, and a spring member 26 is arranged to be elastically deformable in the radial direction, and the spring member 26 has the internal contact point P2. A movable inner contact point P□ is formed in contact with the circular outer circumferential surface of the support shaft 21 in a circumferential phase substantially opposite to P3, and a spring material 26 is formed in the support shaft insertion hole 15.
A disk cartridge that has a contact surface that prevents an external force from being applied to the disk cartridge in an axial or radial direction.
