摘要： Based on a left tooth surface (28) having a maximum accumulated pitch error ALmax (when clockwise direction is a positive direction) and a right tooth surface (29) having a minimum accumulated pitch error ARmin (when clockwise direction is a positive direction), which are conceived to most likely have insufficiently ground portions, a correction value δθ which cancels these accumulated pitch errors for suppressing the accumulated pitch error after grinding is obtained. A reference tooth groove angle θ0 is corrected by the correction value δθ, thereby obtaining the meshing angle θ of the work gear. All teeth detection and signal processing in a short period of time is realized by using a displacement sensor and a high-speed meshing-dedicated circuit board.

摘要： A disc device (100) implements information processing with respect to, for example, a zeroth recording layer of an optical disk by an information processing section (510), and outputs a double-layer main voltage value and a double-layer sub voltage value corresponding to the intensities of a zeroth-order light beam and ±first-order light beams which are received by a photodetecting element (350) to an offset calculating section (522) by a voltage value acquiring section (521). The voltage value acquiring section (521) stores voltage values corresponding to the intensities of the zeroth-order light beam and ±first-order light beams which are received by the photodetecting element (350) as a single-layer main voltage value and a single-layer sub voltage value in a memory (400) in a state where a single-layer disc is loaded. The offset calculating section (522) calculates a voltage value corresponding to the intensity of a stray light beam that is reflected by a first recording layer not intended for information processing as an offset voltage value on the basis of the respective voltage values.

摘要： It is an object of the present invention to provide an optical pickup astigmatism adjusting method capable of easily correcting an astigmatism even if the spot shape of a light beam converged on an optical disc is not a true circle. An optical pickup astigmatism adjusting system of the present invention finds an inter-focal distance L0 between a focal position where a light beam is converged in RAD direction and another focal position where a light beam is converged in TAN direction, and a further inter-focal distance L45 between a focal position where a light beam is converged in a direction inclined 45 degrees from RAD direction and another focal position where a light beam is converged in a direction inclined 45 degrees from TAN direction, thereby measuring an astigmatism in accordance with the inter-focal distances L0 and L45. Then, an installation angle of a reflection mirror is adjusted in accordance with the inter-focal distances L0 and L45, thus correcting the astigmatism.

摘要： An information recording/reproducing apparatus includes an optical device, a photo-detector and a calculation unit. The optical device irradiates light beams, including one main beam and at least two sub-beams with respect to an information recording medium. The photo-detector receives return lights of the main beam and sub-beams to output light detection signals. The calculation unit produces a tracking error signal and a position information signal based on the light detection signals. The optical device irradiates the at least two sub-beams onto positions shifted to opposite sides of a center of the guide track, respectively, when the main beam is being irradiated onto a center of the information recording track. Thus, the apparatus produces the tracking error signal and the position information signal by utilizing a common optical system and a common signal processing system and thereby executes tracking servo control and random access processing with high accuracy.
