リッジ。A disk 2 is rotatably housed in a disk case 1 having a drive shaft insertion window 3, and this disk 2 is integrally connected to a disc-shaped seat 9 and the center portion of the seat 9, and faces the drive shaft insertion window 3. The hub 10 has a spindle insertion hole 14 in the center thereof, and annular guide grooves 15 are formed in the upper and lower end surfaces of the hub 10 on the outer periphery around the hub center P. An engagement rib 16 is formed at one location in the circumferential direction of each of the guide grooves 15 to cross the guide groove 15, and when the disc drive is loaded, the engagement rib 16 is formed between the hub pedestal 17 and the collet 21, which are installed facing each other on the disc drive side. The upper and lower end surfaces of the hub 10 are sandwiched and held, and the support shaft 19 protruding from the hub receiving surface 18 of the JS holder 17 engages in the supporting shaft insertion hole 14, and the supporting shaft 19 protruding from the hub receiving surface 18 is inserted into the supporting shaft insertion hole 14. In a disk cartridge in which the drive shaft 20 engages in the guide groove 15 and the engagement rib 16 abuts and engages, a hub holder 1 is provided on the upper and lower end surfaces of the hub 10.
a first reference surface 50 that is in contact with the hub receiving surface 18 of No. 7; and a second reference surface 51 that is radially inner than the reference surface 50 and that the tip end surface of the collet 21 is in contact with; The engagement rib 16 is located between the first reference surface 50 and the second reference surface 51, the second reference surface 51 is lower than the first reference surface 50, and the retaining rib 16 is lower than the second reference surface 51. A disc cartridge characterized in that each height is set to be lower than the other.
