| 20120127546 | HOLOGRAM LAMINATE AND METHOD OF MANUFACTURING HOLOGRAM LAMINATE - A hologram laminate is provided with a hologram recording layer in which holograms are recorded, a first bonding layer, a pattern layer having a first region and a second region, and a second bonding layer. The hologram recording layer, the first bonding layer, the pattern layer, and the second bonding layer are laminated in this order. Detaching strength of the first bonding layer is larger than detaching strength of the second bonding layer. The detaching strength of the second bonding layer with respect to the first region and the detaching strength of the second bonding layer with respect to the second region are different. | 05-24-2012 |
| 20120113789 | READ-ONLY OPTICAL RECORDING MEDIUM - [Object] To provide a durable read-only optical recording medium having less variances in characteristics of a metal reflective film due to a temporal change. | 05-10-2012 |
| 20120087222 | DISC INSPECTING METHOD AND DISC INSPECTING DEVICE - A disc inspecting method includes: forming recording marks on a disc; scanning the recording marks from inside to outside or from outside to inside of the disc by a pickup unit to read a reproduction signal while rotating a spindle to move a slider by each predetermined width; acquiring reproduction data from the reproduction signal in a signal acquiring unit; and determining whether or not the reproduction data is proper in a calculation unit, and optimizing a formation condition of the recording marks when it is determined that the reproduction data is not proper. | 04-12-2012 |
| 20120007946 | HOLOGRAM REPRODUCTION IMAGE PROCESSING APPARATUS AND PROCESSING METHOD - A holographic reproduction image processing apparatus includes: a detecting section detecting the luminance of a plurality of pixels in an area of a holographic reproduction image extending in a direction substantially orthogonal to a direction in which the image has luminance variation; and an image processing section correcting the luminance variation according to luminance information supplied from the detecting section. | 01-12-2012 |
| 20120005441 | COPYING APPARATUS, COPYING METHOD, MEMORY MEDIUM, AND PROGRAM - A copying apparatus is used for copying data stored in a memory medium including a memory unit storing the data therein and having a management data area in which unique information of the memory medium is stored and a user data area into which user data is written, as a master medium to the memory medium as a copy destination medium. The copying apparatus includes: a memory means for storing an image data file of the master medium and the unique information that is stored in the management data area of the master medium therein; a reading/writing unit that writes or reads data on or from the installed copy destination medium; and a control unit that is configured so as to perform a necessary control process by operating an operating system based on an application program. The control unit performs a file/folder recognizing process and a writing control process. | 01-05-2012 |
| 20120002257 | HOLOGRAM RECORDING MEDIUM AND METHOD FOR MANUFACTURING THE SAME, HOLOGRAM REPRODUCTION APPARATUS, AND HOLOGRAM REPRODUCTION METHOD - A hologram recording medium having two or more images recorded therein, wherein when substantially collimated light is incident along a first direction on the hologram recording medium, a first image is reproduced with the intensity of light diffracted in the hologram recording medium maximized in a predetermined direction, when substantially collimated light is incident along a second direction on the hologram recording medium, a second image is reproduced with the intensity of light diffracted in the hologram recording medium maximized in the predetermined direction, and a full width at half maximum of a reproduction angle of at least either of the diffracted light intensities of the first and second images is 8° or smaller. | 01-05-2012 |
| 20110207035 | Exposure apparatus and exposure method - An exposure apparatus includes an exposure unit selectively performing exposure on a resist layer with a first laser beam, focused by a lens system, in a pattern including pits and lands arranged in a scanning direction; a detecting unit detecting a reflection of a second laser beam applied through the lens system to the resist layer selectively exposed to the first laser beam, the second laser beam being produced by changing a focal length of the lens system such that the resist layer is prevented from responding thereto; a calculating unit calculating, from a result of the detection, a displacement between center axes of signal waveforms representing beams reflected from first and second portions of the pattern having a smallest width and a larger width, respectively; a setting unit setting the focal length of the lens system to such a value that the displacement is maximal; and a control unit controlling the exposure unit to expose the resist layer to the first laser beam focused with the focal length set by the setting unit. | 08-25-2011 |
| 20110199660 | Hologram recording medium - A hologram recording medium includes: a hologram recording layer; and a light scattering layer, wherein a material having a reflection characteristic different from that of a main material forming the light scattering layer is arranged in the light scattering layer. | 08-18-2011 |
| 20110188102 | Hologram-including medium, hologram-including medium producing apparatus, and information authentication method - A hologram-including medium is disclosed, which is an integrated medium on which at least two items of identification information are recorded, wherein one of the two items of identification information is holographic identification information which can be observed within a predetermined angle. | 08-04-2011 |
