Claims

[Scope of utility model registration request]

A disk 2 is rotatably housed in a disk case 1 having a drive shaft insertion window 3 and a magnetic head insertion window 4, and the disk 2 has a disk-shaped sheet 11 with a hole 9 in the center.
and a hub 12 that clamps the peripheral edge of the central hole 9 of the sheet 11.
and the end surface 12a of the hub 12 is the disk case 1.
The hub 12 has a solid shaft insertion hole 22 in the center into which the solid shaft 25 on the magnetic recording device side is inserted, and a drive shaft into which the drive shaft 26 on the magnetic recording device side enters. Insertion hole 24
In the disk cartridge, the solid shaft insertion hole 22 has two internal contact points P inscribed with the circular outer peripheral surface of the solid shaft 25.
2.P3, and the drive shaft insertion hole 26 has a contact surface 32 that is circumscribed by the circular outer circumferential surface of the drive shaft 26. Line contact of the drive shaft 26 with the contact surface 32 causes the solid shaft to connect to the solid shaft 25. Insertion hole 2
2. A disk cartridge characterized in that two points P2 and P3 on the inner surface of the disk cartridge are received and supported.
