PROBLEM TO BE SOLVED: To provide slot-in-mechanism of a cartridge specification which has opening and closing mechanism at a side face and in which seating pre-load is given through a holder. SOLUTION: A holder 11 is continued to descend further even the cartridge 1 is abutted on a receiving mount 6b. A press roller B (12) is raised with the descent, however when a press roller shaft 12b is abutted on the holder 11, the roller B cannot be raised more. Consequently, descent pressure of the holder 11 is operated directly to the upper surface of the cartridge 1. Thereby, the cartridge 1 is pressed to the receiving mount 6b, and the disk unit having high seating performance in which a position never be changed even if vibration and impact are applied can be realized.
