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： It is an object of the present invention to adjust the focus position of an optical pickup. A brightness measuring apparatus having a half mirror and an objective lens focusing on the half mirror is disposed at a position facing an optical pickup PUi, in a manner such that the objective lens OB of the optical pickup PUi faces the half mirror. Then, the optical pickup PUi is operated to start a focus servo, while the position of multi-lens provided in the optical pickup PUi is changed continuously, thereby measuring a highest brightness of a spot light image incident on the half mirror through the objective lens, by virtue of the brightness measuring apparatus. Subsequently, a highest brightness change caused by changing the position of the multi-lens ML is inspected so as to fix the multi-lens ML at a position when the maximum highest brightness has been obtained, thereby effecting an optimum focus position adjustment for an optical pickup.

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.
