Recording disk cartridge, and assembling method and assembling apparatus thereof

An assembling method of a recording disk cartridge,

• wherein said recording disk cartridge integrally rotatably houses said center cores, where a plurality of flexible recording disk media are fixed, within a cartridge case thereof through said spacers;
• wherein the cartridge case comprises a lower plate for configuring a lower wall parallel to the plurality of said recording disk media, at least one inner plate that is stacked and fixed on said lower plate and partitions the plurality of said recording disk media, and an upper plate that is stacked and fixed on said inner plate and configures an upper wall of said cartridge case;
• and wherein in each of said spacers are formed stop protrusions that can fit in stop holes each of said center cores, and holding depressions having a constant positional relationship with said stop protrusions, and in said center core is dispensed an identification sign for indicating positions of said stop holes,
• wherein in stacking said center core where said recording disk media are fixed within said cartridge case, the assembling method comprising the processes of:
• detecting said identification sign of said center core, and placing the center core in a constant direction;
• and
• gripping holding depressions of said spacer by a chucker, and positioning and fitting stop protrusions to/in stop holes of said center core placed.
