(JA) 光ディスク再生装置
Abstract: front page image
(EN)Provided is an optical disc reproducing device which corrects spherical aberration by moving a collimator lens (22), which is to be used for spherical aberration correction, to correct positions for all the reproducible media.  The optical disc reproducing device is provided with a reference position detecting section (30), which detects a reference position of the collimator lens; and a spherical aberration correction driver (11), which moves the collimator lens to a correct position for the furthest medium from the reference position or further in predetermined timing.
(FR)L'invention concerne un dispositif de reproduction de disque optique qui corrige l'aberration sphérique par déplacement d'une lentille de collimation (22), à utiliser pour la correction de l'aberration sphérique, pour corriger des positions pour tous les supports reproductibles. Le dispositif de reproduction de disque optique est pourvu d'une section détection de position de référence (30), qui détecte une position de référence de la lentille de collimation; et un lecteur de correction d'aberration (11), qui déplace la lentille de collimation vers une position correcte pour le support le plus éloigné de la position de référence ou encore en synchronisation prédéterminée.
(JA) 球面収差補正用コリメータレンズ22を再生可能な全てのメディアに対する適正位置に移動させて球面収差の補正を行う光ディスク再生装置において、球面収差補正用コリメータレンズの基準位置を検出する基準位置検出部30と、基準位置から最も遠いメディアに対する適正位置以上の位置まで球面収差補正用コリメータレンズを所定のタイミングで移動させる球面収差補正ドライバ11とを備えた。
