Title (EN) DYE FOR OPTICAL INFORMATION RECORDING MEDIUM AND OPTICAL INFORMATION RECORDING MEDIUM
(FR) COLORANT POUR SUPPORT OPTIQUE D'ENREGISTREMENT D'INFORMATIONS ET SUPPORT OPTIQUE D'ENREGISTREMENT D'INFORMATIONS
(JA) 光情報記録媒体用色素及び光情報記録媒体
Abstract:
(EN) Provided is an optical information recording medium employing an in-groove recording system, and having a preferable recording characteristic with a high modulation degree and low jitter characteristics. The medium is comprised of a circular-disk shaped substrate (2) having a through hole at a center portion thereof and a helically formed guide groove (3) on one surface thereof; a reflection layer (4) formed on the guide groove (3) of the substrate (2); a recording layer (5) formed on the reflection layer (4) and composed of an organic material including a dye; a protection layer (6) provided on the recording layer (5); and a light transmission layer (6) formed on the protection layer (6).  The recording layer (5) includes an organic dye which is an azo metal complex compound having a structure represented by (Chemical formula 1) and a functional group represented by (Chemical formula 2).
(FR) L'invention porte sur un support optique d'enregistrement d'informations utilisant un système d'enregistrement dans les sillons, et présentant une caractéristique d'enregistrement préférable avec un degré de modulation élevé et des caractéristiques de gigue faibles. Le milieu est composé d'un substrat en forme de disque circulaire (2) présentant un trou traversant à une position centrale correspondante et une rainure de guidage formée hélicoïdalement (3) sur une surface correspondante ; une couche de réflexion (4) formée sur la rainure de guidage (3) du substrat (2) ; une couche d'enregistrement (5) formée sur la couche de réflexion (4) et composée d'un matériau organique renfermant un colorant ; une couche de protection (6) disposée sur la couche d'enregistrement (5) ; et une couche de transmission de lumière (6) formée sur la couche de protection (6). La couche d'enregistrement (5) renferme un colorant organique qui est un composé complexe azo-métal présentant une structure représentée par (formule chimique 1) et un groupe fonctionnel représenté par (formule chimique 2).
(JA)  記録方式がIn-Groove記録である光情報記録媒体において、変調度が高く、ジッタ特性が低い良好な記録特性を有する光情報記録媒体を得る。  中心部分に貫通孔を有しかつ一方の面側に螺旋状に形成された案内溝3を有する円板状の基板2と、前記基板2の前記案内溝3上に形成された反射層と4、前記反射層4上に形成されかつ色素を含む有機物質で構成された記録層5と、前記記録層5上に設けられた保護層6と、前記保護層6上に形成された光透過層6と、を有する。記録層5は、(化1)に示す骨格と、(化2)に示す官能基を有するアゾ系金属錯体化合物である有機色素を含む。
