A disk cartridge (21) for loading on a flat tray (1) included in a disk loading apparatus. Recesses (29) are provided on the back side of the disk cartridge near the rear end (27a) thereof, and projections (16) are provided on the tray for judging whether the disk cartridge is loaded properly on the tray. In addition, notches (30) are formed on the right (27d) and left (27c) sides of the disk cartridge between the recesses and the rear end thereof for engagement with an automatic cartridge-changer.

Disk cartridge with judging recesses

A disk cartridge (21) for loading on a flat tray (1) included in a disk loading apparatus, wherein positioning holes (28) are provided at the rear end (27a), on a peripheral side, of the disk cartridge, and protrusions (18) are formed on the tray providing for a rigid positioning of the cartridge in order to fix the cartridge at the specified position on the tray. In addition, a groove (32) is formed on the face side and on the back side of the cartridge extending in a lateral direction, and a resin flow inlet (33) is provided at the rear end (27a) to improve the productability of a thin portion (26) of the cartridge.

Disk cartridge with positioning hole

A flat tray (1) for receiving a disk cartridge (21) for a disk loading apparatus, wherein positioning holes (28) are provided at the rear end (27a), on a peripheral side, of the disk cartridge, and protrusions (18) are formed on the tray providing for a rigid positioning of the cartridge in order to fix the cartridge at the specified position on the tray. The protrusions (18) may be made of leaf springs that are formed with one end curved. When the disk cartridge (21) is pushed into the tray (1), the curved portions of the protrusions match the positioning holes (28) on the disk cartridge.

Tray with positioning protrusion for loading a disk cartridge

A disk cartridge (21) for loading on a flat tray (1) included in a disk loading apparatus, wherein an inclined groove (32) is formed on the face side (22a) and the back side (22b) of the disk cartridge to extend in the moving direction of the shutter (23). A resin flow inlet (33) is provided at the rear end (27a) to improve the productability of the thin part of the cartridge. The inclination of the groove enables to detect when a wrong side of the disk cartridge is put on the tray.
