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 inserted hole is formed so as to extend from an approximately center of an edge surface of an inserting direction to the drive apparatus to a direction contrary to the inserting direction. An upper accommodating portion 21 having a swelling shape is formed on an upper surface of the upper half 2 and an approximately straight upper portion of the lower head inserted hole. Thus, an edge surface opening which contacts the lower head inserted 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 inserted 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 inserted 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.

Description of the invention (1 4), the disc cartridge can be completely inserted and closed by the box 1 when it is inserted, so it can also prevent dust during use Enter the drive. As described above, on the upper surface lu of the case 1, there is no manhole for inserting the pickup head provided in the conventional disc cartridge. Therefore, the strength of the case 1 is higher than that of the conventional disc case. In addition, since the inclined portions 21b, 23b, 24Rb, and 24Lb are provided, the strength of the upper case in the bending direction is significantly improved compared to a case where the surface is flat. This is considered to be because the forces in the bending direction are dispersed by the inclined portions 21b, 23b, 24Rb, and 24Lb. Since the highest faces 21a, 23a, 24

The heights of Ra and 24La are set to the same height. When a plurality of magazines are stacked and stored, each magazine will not shake. The recessed portion (lowest surface portion 2 2) surrounded by the protruding portion is also not scratched when the disc cartridges are stacked, so the recessed portion can be used as a field for diamond labeling. Next, the configuration of the lower half 3 will be described. The surface of the lower half 3 is formed approximately flat. However, the sliding area 31 of the shutter 4 is reduced in height compared to the main surface area 32 of the lower half by the thickness of the long crotch portion 41 of the shutter 4. Thereby, the surface of the long side portion 41 of the shutter 4 does not protrude from the main surface area 32 of the lower half portion 3. This means that when a plurality of magazines are stacked, there is no shaking between the magazines. Also in the sliding area 31, a step portion 33 is formed at the end portion near the front surface 1F. This step portion 3 3 is slightly lower than the sliding area 3 1. In this step portion 33, a slit-like engaging hole 34 is formed between an end portion close to the front surface 1F of the case 1 and the main surface area 32. The front end portion of the long side portion 41 of the shutter 4 is inserted into the engaging hole 34 and fastened. The shutter of the conventional disc M box is formed into a channel-shaped cross section so as to contact the upper and lower sides of the box body.
