PURPOSE:To obtain a tracking error signal having no offset error by decomposing the tracking error signal into a part generating at a land part and a part generated at a pit part, and detecting an offset quantity from the tracking error signal generated at the land part. CONSTITUTION:An RF ...
摘要: PURPOSE: To detect a tracking error by a differential push-pull method without being affected by the influence of the ID part of an adjacent track.收藏 引用 批量引用 报错 分享 文库来源 求助全文 TRACKING ERROR DETECTING DEVICE FOR OPTICAL HEAD 优质文献 ...
Error detecting device for optical head ofAn error detecting device for an optical head detects a focussing error and a tracking error. The error detecting device comprises optical means for converting a reflected light of a light irradiating a surface to be irradiated into an... K Fukui,A ...
PROBLEM TO BE SOLVED: To provide a tracking error signal detecting device that the problem of an offset due to differences among gain characteristics and/or pit depths is solved by improving the split structure of an octapertite photodetector, and to provide a reproduced signal detecting device ...
An arrangement for detecting and tracking a target contains a sensor which responds to electromagnetic radiation. It automatically optimises the distinction between the target and the terrain and is very simple. The measurement values produced by the sensor are reduced to two intensity levels for the...
PURPOSE:To realize stable tracking servo control by correcting a tracking error signal according to a tracking offset signal based on the quantity of light of a light flux detected from a third area provided in the vicinity of the center of the optical axis of a diffraction grating. CONSTITUTION...
