Title (EN) OPTICAL DISC JUDGMENT METHOD AND OPTICAL DISC DEVICE
(FR) PROCEDE D'ANALYSE DE DISQUE OPTIQUE ET DISPOSITIF DE DISQUE OPTIQUE
(JA) 光ディスク判別方法及び光ディスク装置
Abstract: front page image
(EN)An optical disc device record data or reproduce data to/from a plurality of types of optical discs including a recording-enabled optical disc and a reproduction-dedicated optical disc manufactured according to the BD standard. The device includes: means (506, 507) for applying a light beam to a management area (502) of an optical disc (501) in the state not performing tracking control and generating a track position signal (push-pull TE or phase difference TE) from the light reflected from the management area (502); and disc judgment means for judging whether the optical disc (501) mounted on the optical disc device is a recording-enabled disc or a reproduction-dedicated disc according to the track position signal obtained from the management area (502).
(FR)La présente invention concerne un dispositif de disque optique qui enregistre des données ou reproduit des données sur/à partir d'une pluralité de types de disques optiques, y compris un disque optique permettant l'enregistrement et un disque optique dédié à la reproduction fabriqué selon la technologie BD. Le dispositif comprend les éléments ci-après. Des éléments (506, 507) appliquent un faisceau lumineux à une zone de gestion (502) d'un disque optique (501) sans exécution de commande d'asservissement et génèrent un signal de position de piste (signal TE push-pull ou signal TE de déphasage) d'après la lumière réfléchie par la zone de gestion (502). Des éléments d'analyse de disque établissent si le disque (501) placé dans le dispositif de disque optique permet l'enregistrement ou s'il est dédié à la reproduction d'après le signal de position de piste obtenu de la zone de gestion (502).
(JA) 本発明の光ディスク装置は、BD規格に従って製造された記録可能光ディスクおよび再生専用光ディスクを含む複数種類の光ディスクに対してデータを記録すること、および光ディスクからデータを再生することの少なくとも一方を実行する光ディスク装置である。この装置は、トラッキング制御を行わない状態で光ビームを光ディスク501の管理領域502に照射し、管理領域502によって反射された光からトラック位置信号(プッシュプルTEまたは位相差TE)を生成する手段(506、507)と、管理領域502から得られるトラック位置信号に基づいて、光ディスク装置に装填された光ディスク501が記録可能光ディスクおよび再生専用光ディスクのいずれであるかを判別するディスク判別手段とを備える。
