要約
(EN)
In a case where (i) a reflectance calculated from a reflected light amount obtained from a longest pit (P1max) or a longest space (S1max) in a first pit row is defined as a first reflectance and (ii) a reflectance calculated from a reflected light amount obtained from a longest pit (P2max) or a longest space (S2max) in the second pit row is defined as a second reflectance, the first pit row is formed such that the first reflectance becomes substantially identical with the second reflectance.
(FR)
Selon la présente invention, si un premier taux de réflexion est défini en tant que taux de réflexion calculé à partir de la quantité de lumière réfléchie obtenue à partir du creux le plus long (P1max) ou de l'espace le plus long (S1max) dans une première rangée de creux et un second taux de réflexion est défini en tant que taux de réflexion calculé à partir de la quantité de lumière réfléchie obtenue à partir du creux le plus long (P2max) ou de l'espace le plus long (S2max) dans une seconde rangée de creux, la première rangée de creux est conçue de sorte que le premier taux de réflexion soit sensiblement le même que le second taux de réflexion.
