Abstract: front page image
(EN)An information recording medium comprises first and second recording layers (107, 207) for recording information. The first and second recording layers each have a groove track (GT) having the same track pitch and adapted to record the information and are preformatted (109, LPP) for producing a clock used in recording so that the recording densities of the recorded information in the layers are different.
(FR)L'invention concerne un support d'enregistrement d'informations comportant une première et une deuxième couche d'enregistrement (107, 207) destinées à l'enregistrement d'informations. La première et la deuxième couche d'enregistrement comportent chacune une piste rainurée (GT) présentant le même pas transversal, conçues pour l'enregistrement d'informations, et sont pré-formatées (109, LPP) pour la création d'une horloge employée lors de l'enregistrement, de telle manière que les densités d'enregistrement des informations enregistrées sont différentes.
(JA) 情報を記録するための第1記録層(107)と第2記録層(207)とを備えており、第1記録層及び第2記録層は、同一のトラックピッチからなり前記情報を記録するためのグルーブトラック(GT)を有し、各層に記録される前記情報の記録密度が相異なるように、記録時のクロックを生成するためのプリフォーマット(109、LPP)がなされている。
