20100110865 - Optical information recording and reproducing apparatus, and cartridge: An optical information recording and reproducing apparatus relating to the invention employs a two-beam interference method. In the optical information recording and reproducing apparatus, a moving device moves an information recording medium between a recording and reproducing position and a retracting position, and a mirror moves together with the information... Agent: Cohen, Pontani, Lieberman & Pavane LLP

20100110866 - Optical disc reproducing light quantity setting method and optical disc apparatus: In a method of setting a quantity of light directed onto an optical disc for reproduction purposes, an area of the optical disc in which information has been recorded is reproduced with a test-reproducing light quantity (S14, S24), a reproduction time or number of reproductions up to the time when... Agent: Birch Stewart Kolasch & Birch

20100110867 - Disc playback apparatus: A disc playback apparatus characterized in, when receiving either a fast-forward playback request or a fast-backward playback request, calculating a target address by setting up a position which is close to a position at which information being read from a memory and being played back is stored in a disc... Agent: Birch Stewart Kolasch & Birch

20100110868 - Optical recording medium, information recording method, and information reproducing method: According to one embodiment, an optical recording medium is provided in which interlayer crosstalk is low and in which stable and high-quality recording characteristics can be obtained. To this end, an optical recording medium comprises a first recording part which includes a first recording layer and a first light reflecting... Agent: Oblon, Spivak, Mcclelland Maier & Neustadt, L.L.P.

20100110869 - Information recording carrier and information reproducing apparatus for the same: Plural grooves or lands formed in an information recording carrier include at least a wobbling region and data is recorded wobblingly in this wobbling region by phase shift modulation while recorded digitally with a single or multiple waves as a channel bit.... Agent: The Nath Law Group

20100110870 - Optical information recording medium, and substrate and manufacturing method for the optical information recording medium: In an optical disk including at least a rewritable phase change material and comprising a recording layer having a reflectivity of more than 15%, an address output value as an address pit signal component occupying in a reproduced signal in a non recording state is prescribed to be 0.18 though... Agent: Connolly Bove Lodge & Hutz LLP

20100110871 - Optical information recording medium: The recording/reproducing quality of a multilayer optical information recording medium deteriorate not only due to interference from other layers caused by light converging on other information layers but also due to stray light converging on the surface of a protective layer and stray light that does not converge on other... Agent: Wenderoth, Lind & Ponack L.L.P.
