Abstract: There is provided a cartridge including a running portion which causes both end portions of a disc-shaped recording medium to run, and a pressing portion which presses one end portion of the disc-shaped recording medium to press the other end portion against the running portion. Static friction coefficients of a portion of the pressing portion coming in contact with the one end portion and a portion of the running portion coming in contact with the other end portion are different.

Abstract: Some embodiments of the invention provide a computerized method for creating a scene selection from a marker for a multi-image content. The method allows identification of a multi-image content. The multi-image content includes several markers. Each marker represents an image of the multi-image content. The markers are identified to generate several scenes. Each generated scene is referenced to its corresponding marker from which it is identified.

Abstract: A cartridge 2 receiving a photosensitive recording disc 4 therein including: a cartridge body 11 having inner openings 18 and 19 exposing part of the recording disc 4 to the outside; a light-shield plate 12 attached to the outside of the cartridge body 11 and having outer openings 14 and 15 which face the inner openings 18 and 19; and a shutter 13 opening/closing the inner openings 18 and 19 and the outer openings 14 and 15 between the cartridge body 11 and the light-shield plate 12; wherein recesses 25e and 26e for inserting end edges 12d of the outer circumference of the light-shield plate 12 are provided in light-shield plate attachment surfaces 25a and 26a of the cartridge body 11 so that when the end edges 12d are inserted into the recesses 25e and 26e and attached to the cartridge body 11, a labyrinth-shaped light-shielding structure is formed.

Abstract: A method of presenting a data storage diskette to a user is disclosed. The method includes the steps of providing the diskette and promoting that handwritten indicia be deposited directly onto an information field in labeling the diskette. In this regard, the diskette includes a housing defining first and second housing sections, and an exterior portion of at least one of the housing sections integrally forming the information field.

Abstract: A cartridge for an optical data storage disc includes a sheet metal sheath that is folded back on itself and a plastic insert that is inserted into the sheath. An opening is formed in the plastic insert for holding an optical data storage disc. The sheath includes two wall portions that are located on opposite sides of a bend area, where the sheet metal is folded. The two wall portions are attached to each other, preferably by spot-welding, to form a structurally stable sandwich that includes the plastic insert between the wall portions. The opening in the plastic insert becomes a cavity for holding the disc. A shutter opening is formed in one of the wall portions, and spindle openings are formed in both wall portions. A shutter covers the shutter opening when the cartridge is not operational to protect the disc. The disc is rotated by the spindle of an external disc drive which enters a central hole of the disc through the spindle openings.

Abstract: An optical disc cartridge for storing an optical disc. The cover of the optical disc cartridge absorbs or filters ambient light which may damage information stored on the disc after prolonged exposure to the ambient light. Preferably, the disc cartridge cover allows some visible light to pass in order to allow a user to read label information on the disc. The color of the cover may be transparent to visible light, allow only specific visible wavelengths of light to pass, or be opaque, as long as the amount of ambient light reaching the disc stored within the disc cartridge is reduced. The disc cover may be made of a single layer or include a base layer with one or more thin films thereon.

Abstract: A recording medium cartridge which is capable of preventing a drop in aesthetic quality by preventing damage to a printed layer for writing during ultrasonic welding is presented. As a printed layer (20), a writing-enabling filler (21), and resin particles (22) having an average particle diameter equal to or greater than the average particle diameter of the writing-enabling filler (21) mentioned above are included in an ink (23). The resin particles (22) come into contact with a welding horn (9), and prevent the writing-enabling filler (21) from falling out or changing shape due to ultrasonic vibration.
