Title (EN) INFORMATION RECORDING MEDIUM AND PROCESS FOR PRODUCING THE SAME
(FR) SUPPORT D'ENREGISTREMENT D'INFORMATIONS ET SON PROCÉDÉ DE PRODUCTION
(JA) 情報記録媒体及びその製造方法
Abstract: front page image
(EN)An information recording medium (9) is provided with an information layer (9a) in which non-planar marks are formed, and a recording layer (13) containing Te, O, and M (where M is at least one element selected from the group comprising Pd, Au, Pt, Ag, Cu, and Ni) which is included in the information layer (9a) and has recordable marks formed therein by using laser irradiation to change the optical properties thereof. In addition, the reflectance (Ra) before laser irradiation and reflectance (Rb) after laser irradiation of this information recording medium (9) satisfy the relationship 1.0 < Rb/Ra < 1.1.
(FR)L'invention porte sur un support d'enregistrement d'informations (9) qui comporte une couche d'informations (9a) dans laquelle des marques non planes sont formées, et une couche d'enregistrement (13) contenant Te, O et M (où M est au moins un élément choisi dans le groupe constitué de Pd, Au, Pt, Ag, Cu et Ni) qui est incluse dans la couche d'informations (9a) et présente des marques enregistrables formées dans celle-ci à l'aide d'une exposition à un laser pour changer les propriétés optiques de celle-ci. De plus, la réflectance (Ra) avant exposition au laser et la réflectance (Rb) après exposition au laser de ce support d'enregistrement d'informations (9) satisfont la relation 1,0 < Rb/Ra < 1,1.
(JA) 情報記録媒体(9)は、凹凸マークが形成された情報層(9a)と、情報層(9a)に含まれ、レーザ照射によって光学的特性が変化することで、追記マークが形成され、Te、O、及びM(MはPd、Au、Pt、Ag、Cu、及びNiから成る群より選択される少なくとも1つの元素)を含有する記録層(13)と、を備える。また、この情報記録媒体(9)は、レーザ照射前の反射率Ra及びレーザ照射後の反射率Rbが、1.0 < Rb/Ra < 1.1 を満たす。
