Abstract:
(EN) The present invention pertains to a disc-like recording medium, a recording device, a recording method, a reproduction device, and a reproduction method that enable recording of data at high density and enable robust reproduction of data recorded at high density. In the disc-like recording medium, a synchronization pattern for synchronizing is recorded on two adjacent tracks in a manner deviating in the track direction so that the positions of the pattern in the track direction do not overlap. The present invention can be applied, for example, to optical discs and other disc-like recording media.
(FR) La présente invention concerne un support d'enregistrement de type disque, un dispositif d'enregistrement, un procédé d'enregistrement, un dispositif de reproduction, et un procédé de reproduction qui permettent l'enregistrement de données à haute densité et une reproduction robuste des données enregistrées à haute densité. Dans le support d'enregistrement de type disque, un modèle de synchronisation destiné à la synchronisation est enregistré sur deux pistes adjacentes avec une déviation dans la direction de la piste, de telle sorte que les positions du modèle dans la direction de la piste ne se chevauchent pas. La présente invention peut être appliquée, par exemple, aux disques optiques et d'autres supports d'enregistrement de type disque.
(JA) 本技術は、データを高密度に記録し、高密度に記録されたデータをロバストに再生することができるようにするディスク状記録媒体、記録装置、記録方法、再生装置、及び、再生方法に関する。 ディスク状記録媒体には、同期をとるための同期パターンが、隣接する2つのトラックで、トラック方向の位置が重複しないようにトラック方向にずれて記録されている。本技術は、例えば、光ディスクその他のディスク状記録媒体等に適用することができる。
