The first sub light reception unit of the photo-detector is shaped so as to reduce reception of noise sub light due to diffraction based on an undesired diffraction pattern of sub light generated the diffraction device. | 2012-05-03 |
20120106312 | OPTICAL PICKUP DEVICE - A first laser light source emits first laser light of a predetermined wavelength, and a second laser light source emits second laser light of a wavelength different from the wavelength of the first laser light. Reflected light of the first and second laser light is entered into an astigmatism portion. The astigmatism portion generates first and second focal lines. A light separating portion separates light fluxes of the reflected light of the first and second laser light from each other, the light fluxes obtained by dividing the reflected light of the first and second laser light into four light fluxes. The light separating portion is constituted of at least one prism having plural slopes, and the photodetector is provided with a common sensor portion which receives the light fluxes of the reflected light of the first and second laser light. | 2012-05-03 |
20120106313 | Optical Disk Device and Optical Disk Discriminating Method - An optical disk discriminating method and an optical disk device which can detect reflected rays for making discrimination among kinds of optical disks with high accuracies. By switching a plurality of lasers and moving a spherical aberration corrector while moving an objective lens to cause it to approach or keep away from an optical disk, rays reflected light from the optical disk can be detected with high accuracies. Discrimination among the kinds of a plurality of optical disks can be made on the basis of signals generated from the detected reflected rays. This ensures that the kind of an optical disk can be determined through one operation of sweeping. | 2012-05-03 |
20120106314 | HIGH DENSITY DATA STORAGE MEDIUM, METHOD AND DEVICE - A composition of matter for the recording medium of nanometer scale thermo-mechanical information storage devices and a nanometer scale thermo-mechanical information storage device. The composition includes: one or more polyaryletherketone polymers, each of the one or more polyaryletherketone polymers having two terminal ends, each terminal end having two or more phenylethynyl moieties. The one or more polyaryletherketone polymers are thermally cured and the resulting cross-linked polyaryletherketone resin used as the recording layers in atomic force data storage devices. | 2012-05-03 |
20120106315 | Efficient Generation of Compensated Signals for Crosstalk Control in a Communication System - An access node of a communication system is configured to control crosstalk between channels of the system. Vectoring circuitry in the access node estimates crosstalk between channels of the system, generates a compressed representation of the crosstalk estimates, and generates compensated signals based on the compressed representation of the crosstalk estimates. The compressed representation comprises a value array and an index array, with the value array comprising selected values from each of a plurality of rows of a matrix representation of the crosstalk estimates, and the index array identifying locations of the selected values in the matrix representation of the crosstalk estimates. The compensated signals may be pre-compensated signals or post-compensated signals. | 2012-05-03 |
