PURPOSE: A disc accommodating cartridge having a disc recognition device is provided to allow a recording/reproducing system to recognize the sate of a disc accommodated in a cartridge case to reduce recording time. CONSTITUTION: A disc accommodating cartridge includes a cartridge case(20), a shutter(30), a cover(40), and a disc recognition device. The cartridge case is constructed in such a manner that upper and lower cases(22,24) in which a plurality of recognition holes(20b,20c,20d), the first and second long holes(20f,20g) are formed are combined with each other to form a disc accommodation space inside the cartridge case. The cartridge case has accommodation holes(22b,24b) at the top and bottom faces thereof. The shutter is movably set at the cartridge case to open/close the accommodation holes. The cover covers the disc accommodation space of the cartridge case. The disc recognition device is placed at the cover to selectively confirm the sate of a disc accommodated in the cartridge case.
