Abstract: A cartridge for encasing optical discs of different diameters and thus permitting to load bare optical discs of different diameters into a disc cartridge-dedicated recorder/player. It includes a cartridge body (2) formed from an upper shell (6) having formed therein an insertion/removal opening (2a) for a first optical disc (3a) and a lower shell (7) having a write/read opening (24) formed therein, the upper and lower shells (6, 7) being butted to each other, a middle shell (4) having formed in the main side thereof an opening (44) corresponding to the opening (24) and which is rotatably received in the cartridge body (2), and a pair of shutter members (5a, 5b) installed on the middle shell (4) at the side of the lower shell (7) and which uncovers the openings (24, 44) when the middle shell (4) rotates until the openings (24, 44) are aligned with each other.

Abstract: A disk cartridge accommodating a disk includes a case receiving the disk and having openings. A shutter opens and/or closes the openings, where the openings deviate a predetermined distance from a middle position of the case toward one side.

Abstract: To make it possible to keep a disk-like recording medium accommodated in a case under a stable state without shaking and to easily take it out, a receiving table on which a center portion of a disk is put is so formed at a base center of a main body as to protrude from a base surface. An outer peripheral edge for supporting thereon a disk outer periphery protrudes from the receiving table as a center. A removable member for supporting the outer periphery of the disk and engaging with the outer periphery is disposed by cutting off a part of the outer peripheral edge. The removable member includes a lift portion for supporting thereon the disk outer periphery, formed inside a rocking lever and a button formed outside the lever. Hooks for engaging with the disk outer periphery are provided to the lever.

Abstract: Apparatus (19) for holding information storage media, such as a CD or DVD, in combination with a releasable security member (8) insertable into the apparatus for inhibiting removal of the storage media from the apparatus, e.g. by inhibiting access to the storage media by locking the apparatus in a closed configuration and/or by locking the storage media to the apparatus. The apparatus is adapted, e.g. by knowing one or more slots (12, 24) therein, to receive part of the security member therein and the security has at least one projection (9A, 10A) for inserting into the apparatus, e.g. through the slot (12, 24). Modification t the apparatus to enable it to receive a security member are described as well as different types of security members. Apparatus for releasing the security member from the apparatus holding the storage media is also described.

Abstract: A hand-held disc storage, deployment and retrieval device includes a housing defining an interior cavity adapted to store a media disc therein. A manually-actuated slider is disposed within the interior cavity and movable along guide tracks formed in the housing between a disc deployment position and a disc retrieval position. A manually-actuated lever mechanism is operably connected to the slider for deploying and retrieving the disc from the housing. Disc tracks and a ramp are formed in the housing for guiding the disc into and out of the interior cavity. Multiple housings may be interlocked in stacking relationship to one another. The disc may also be locked within the housing, or a case provided for locking multiple housings and discs to one another within the case.

Abstract: A disc cartridge according to an aspect of the present invention allows easy draw out and insertion of an optical disc from/into a cartridge, and has a main wall opposite to one surface of an optical disc, a side wall provided in the circumference of the main wall, a disc holding claw extending from the side wall just like holding the optical disc between the main wall, and a handling area.
