Abstract: A disk cartridge of the present invention comprises a case body having a disk-storage portion and an opening/closing cover having a pair of disk holding members that hold a disk in its inplane direction. A grip of the opening/closing cover engages with a grip-guide part of the case body. They may be formed asymmetrically with respect to the center line of the opening/closing cover in its insertion direction, thus preventing the opening/closing cover from being inserted into the case body upside down.

Abstract: A disc cartridge adaptor for housing a information storage disc and a disc holder. The disc cartridge adaptor includes: a case body including a housing portion for rotatably housing the disc, and an opening communicating with the housing portion for allowing insertion and removal of the disc holder and the disc. A lid is pivotably supported by the case body. The housing portion is able to house the disc together with the disc holder or without the disc holder. The lid includes a positioning member movable between a first position and a second position with respect to the lid. The positioning member is in the first position restricting the position of the disc within a predetermined range when the disc is housed in the housing portion without the disc holder, and retreats to the second position when the disc holder is housed in the housing portion.

Abstract: A disk cartridge of the present invention comprises a case body (101) having a disk-storage portion and an opening/closing cover (201) having a pair of disk holding members (202) that hold a disk (10) in its inplane direction. The accommodated disk (10) is loaded together with the opening/closing cover (201) into an adapter having compatibility with a large disk cartridge. Thus, information can be, for example, reproduced from the disk (10) in a drive unit designed for a large disk cartridge via the adapter. Moreover, a series of operations can be conducted without touching the disk directly.

Abstract: The disk cartridge adapted for permitting the removal of a disk comprises a case having a disk slot for receiving a disk, an opening provided so that a disk motor and pickup can be inserted into the disk case, a disk access provided between two adjacent side walls of the case to communicate with the disk slot allowing the disk to pass through the slot, and a lid rotatably supported on the case for opening and closing the disk access, in which a disk guide passage is formed so that, when the lid is open, the disk moves a specific distance along the inner surface of the side wall of the case, abuts against the lid to change the moving direction of the disk, and is discharged from the disk access.
