(EN) The invention discloses an optical information recording medium and a reproduction method. 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.
(ZH) 本发明为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。
