  • Patent number: 8561093
    Abstract: This disclosure relates to thin optical storage media that may be compliant with conventional DVD drives. Unlike conventional DVDs, however, the described media generally has a thickness profile less than 1.2 mm. The media may further include one or more protrusions protruding from a major surface of the media which define a thickness of approximately 1.2 mm within the clamping area of the media. In some embodiments, the media may further include one or more recesses recessed into a major surface within the clamping area of the media. Two or more optical storage media may be packaged by stacking the media in a configuration that defines an overall stacked thickness that is less than 1.2 mm for each individual medium in the package.

  • Patent number: 7694225
    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.

  • Patent number: 7458088
    Abstract: An intermediate for an optical recording medium, according to the present invention, is an intermediate produced beforehand for manufacturing an optical recording medium that has a central mounting hole formed in a central portion thereof and one or more kinds of functional layers formed on a surface thereof, for enabling at least one of information recording and information reproduction. The intermediate has a provisional central hole, which is smaller in diameter than the central mounting hole, formed in a central portion thereof. This makes it possible to drop resin in the vicinity of the center of the intermediate without using a disk-shaped member, in performing spin coating on the intermediate, whereby it is possible to make the layer of applied resin substantially uniform in thickness.

  • Patent number: 7055162
    Abstract: An optical information medium includes a disk-shaped substrate (100) having a center hole (101), an annular information recording area thereon, and an annular resin-based light-transmitting layer (102) thereon by which recording/reading laser beam is transmitted to the information recording area. The light-transmitting layer (102) terminates at a radially inner periphery which forms an annular raised rim (6). The rim is effective for protecting the light-transmitting layer from damages and dust adhesion, and when a plurality of such media are stacked, preventing the media from intimate contact.

  • Patent number: 6865745
    Abstract: An improved optical disc is provided that comprises a substantially transparent substrate, one surface of which carries optical data structures comprising pits and lands radially outward of a clamp area of the disc. In the clamp area a protrusion structure is provided above the first surface to create a clamp thickness greater than the thickness of the rest of the disc. In accordance with the principles of the present invention, only a portion of the clamp area is covered by the protrusions, which emulate a disc having a clamp area of greater thickness. In order to reduce warping caused by shrinkage of material added to the clamp area, the amount of material used to form the protrusions is less than 5% of the amount of material used to form the rest of the clamp area.

  • Patent number: 6779193
    Abstract: A digital data storage assembly (2), e.g., a flexible thin film compact disc, is described. Digital data storage assembly (2) includes, (a) a thin film data storage carrier (11), having substantially opposed first (14) and second (17) surfaces, an aperture (20), and at least one tab (23, 26) extending partially into aperture (20). The assembly (2) also includes, (b) a rigid support (29) having substantially opposed first (32) and second (35) surfaces, and an aperture (38). The assembly (2) further includes, (c) a locking device (41) positioned at least partially around aperture (38) of rigid support (29). Locking device (41) includes at least one shelf (44, 47) extending out over a portion of the first surface (32) of rigid support (29). The shelf (e.g., 44) and a portion (e.g., 53) of the first surface (32) of rigid support (29) residing thereunder together define a tapered slot (e.g., 62), having an open end (59) and a closed end (56).

  • Patent number: 6521540
    Abstract: An improved and new process for fabricating self-aligned contacts (SAC) to source/drain areas of complimentary (CMOS) FET's has been developed using a non-conformal layer of silicon nitride, eliminating the need for a hard mask. This process allows for “zero” spacing from contact structure to polysilicon gate structure, for closely spaced design rule gates. Some key process features of this invention are as follows: no hard mask is needed and the gate process is exactly the same as “standard” logic process. The process differences are that between the S/D implant, salicidation and the normal contact process, there is inserted a non-conformal CVD silicon nitride deposition with a SAC pattern and etch process. The process is fully compatible with both state of-the-art salicide and polycide processes. The self-aligned contact process simplifies processing, while yielding improvements in electrical device performance and reliability.
