<p>[Object] To provide a disk cartridge capable of securing a reliability of an unintentional deletion prevention mechanism. [Solving Means] A disk cartridge according to the present invention includes, between a recordable position and an unrecordable position, a first guide surface (79a) that gradually increases an elastic force of an elastic arm (85) of a tab member (73) and a second guide surface (79b) that gradually decreases the elastic force of the elastic arm (85), and a guide wall (guide portion) (79) on which the guide surfaces (79a, 79b) are formed continuously. Accordingly, it becomes possible to prevent the tab member (73) from stopping at an intermediate position between the recordable position and the unrecordable position and improve a reliability of an unintentional deletion prevention mechanism.</p> |
