Title (EN) OPTICAL DISK DEVICE AND INTERLAYER JUMP METHOD FOR MULTILAYER OPTICAL DISK
(FR) DISPOSITIF À DISQUE OPTIQUE ET PROCÉDÉ DE SAUT INTER-COUCHE POUR DISQUE OPTIQUE MULTICOUCHE
(JA) 光ディスク装置および多層光ディスクにおける層間ジャンプ方法
Abstract:
(EN) Subsequent to the start of an interlayer jump in a multilayer optical disk, the interlayer jump method comprises a step (ST7) for detecting an S-curve signal from the layer preceding a target information layer while the optical aberration has been set so as to correspond to the information layer preceding the target information layer, and a step (ST8) for generating a deceleration signal in the interlayer jump using the detected S-curve signal.
(FR) Après le début d'un saut inter-couche dans un disque optique multicouche, le procédé de saut inter-couche comprend une étape (ST7) destinée à détecter un signal ayant la forme d'une courbe en S provenant de la couche précédant une couche d'informations cibles alors que l'aberration optique a été réglée de façon à correspondre à la couche d'informations précédant la couche d'informations cibles, et une étape (ST8) destinée à produire un signal de décélération lors du saut inter-couche en utilisant le signal détecté ayant la forme d'une courbe en S.
(JA)  本発明の層間ジャンプ方法は、多層光ディスクにおける層間ジャンプを開始した後、目的情報層の手前に位置する情報層に応じた球面収差が行われた状態で、目的情報層の手前の層からS字信号を検出するステップST7と、前記検出されたS字信号を用いて層間ジャンプにおける減速信号を発生させるステップST8とを備えている。
