Claims

[Scope of utility model registration request]

A disk 2 is placed in a disk case 1 having a drive shaft insertion window 3.
is rotatably installed inside, and the disk 2 consists of a seat 9 having a hole 8 in the center and a hub 10 facing the drive shaft insertion window 3,
The hub 10 consists of an upper hub structure 12 and a lower hub structure 13, which are inseparably connected to each other, and both hub structures 12.1
Sheet clamping surfaces 35 and 36 are formed on opposing surfaces of the hub structures 12 and 3, respectively, and are abutted against each other across the peripheral edge of the central hole 8 of the seat 9. The seat positioning portion 3-8, in which the periphery of the central hole 8 is circumscribed at a plurality of points, is radially inner than the seat clamping surface 35°36 and radially inner than the joining portion of both hub components 12°13. A disk cartridge characterized by being provided on the outside.
