(EN) The invention provides an optical information recording medium and a reproduction method. 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.
(ZH) 一种光信息记录介质以及再生方法。在将根据从第1坑点串的最长坑点(P1max)或最长间隙(S1max)获得的反射光量而算出的反射率设为第1反射率、将根据从第2坑点串的最长坑点(P2max)或最长间隙(S2max)获得的反射光量而算出的反射率设为第2反射率的情况下,第1坑点串被形成为第1反射率与第2反射率大致相同。
