要約
(EN) If a first reflection rate is defined as the reflection rate calculated from the quantity of reflected light obtained from the longest pit (P1max) or the longest space (S1max) in a first pit row, and a second reflection rate is defined as the reflection rate calculated from the quantity of reflected light obtained from the longest pit (P2max) or the longest space (S2max) in a second pit row, the first pit row is configured so that the first reflection rate is substantially the same as the second reflection rate.
(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.
(JA)  第1ピット列の最長ピット(P1max)、または、最長スペース(S1max)から得られる反射光量から算出される反射率を第1反射率、第2ピット列の最長ピット(P2max)、または、最長スペース(S2max)から得られる反射光量から算出される反射率を第2反射率とした場合、第1ピット列は、第1反射率が第2反射率と略同一となるように形成されている。
