<P>PROBLEM TO BE SOLVED: To provide an optical disk cartridge that allows a user to reliably discriminate between an upper surface and a lower surface of a case when the user puts a bare disk into the case so as to make the optical disk cartridge. <P>SOLUTION: In an optical disk cartridge comprising: cases 201 and 202 having an opening for accommodating an optical disk; and an opening/closing lid 206 for closing the opening, one end of the opening/closing lid 206 is mounted in a rotatable manner to an end portion of the opening by means of a shaft 207. The opening/closing lid 206 has a recessed portion on a front surface of the opening/closing lid 206 in a label surface side of the optical disk that is accommodated in a case and further has a rotating member 601 mounted in a rotationally movable manner to the recessed portion so as to be able to project toward the front surface side of the opening/closing lid 206 and to be accommodated therein. <P>COPYRIGHT: (C)2012,JPO&INPIT |
