Abstract: PURPOSE: A cartridge having a recognition hole capable of being opened and closed, a method and device for driving the cartridge are provided to open or close the recognition hole according to cartridge open state and disk inspection state to record information in a disk without additional verification when a user certificates the disk state. CONSTITUTION: A cartridge includes a cartridge case for accommodating a disk, an opening cover(40) detachably attached to an opening of the back side of the case, at least one recognition hole(24) used for judging whether or not the disk is out of the cartridge case, and a sensor lever(50) for controlling opening and closing of the recognition hole according to the state of the disk. The sensor lever has an opening/closing member(52) placed in the recognition hole. The cartridge further includes a tension unit(54) extended from the sensor lever to come into contact with the inner side of the cartridge case. The tension unit applies a predetermined tension to the sensor lever and, when the opening cover is opened, locates the opening/closing member of the sensor lever to the open position of the recognition hole to confirm opening of the opening cover. When the opening cover is opened, the opening/closing member of the sensor lever, being located at the closed position of the recognition hole, is automatically moved to the opened position to maintain the open state of the recognition hole.
