ABSTRACT:
A disk-like recording medium is rotatably accommodated in a case 1 configured by opposing an upper half 2 to a lower half 3. A lower head insert hole is formed so as to extend from an approximate center of an edge surface of an inserting direction to the drive apparatus to a direction oppsite to the inserting direction. An upper accommodating portion 21 having an enlarged shape is formed on an upper surface of the upper half 2 and approximately directly overlies the lower head insert hole. Thus, an edge surface opening which connects with the lower head insert hole is formed on an edge surface of the case on a side of the inserting direction to the drive apparatus. Normally, the edge surface opening is closed by a short side portion 42 of a shutter 4 and the lower head insert hole is closed by a long side portion 41 of the shutter 4. When the disk cartridge is inserted in the drive apparatus, the shutter 4 slides in a direction perpendicular to the inserting direction to open the edge surface opening and the lower head insert hole. In this situation, an upper head on the drive apparatus side is inserted in the upper head accommodating portion 21 in an approximately horizontal direction. A lower head on the drive apparatus side is inserted from a lower side in the lower head insert hole. That is, the disk cartridge is loaded in the drive apparatus in a horizontal state.
