    • An information recording medium of the present invention includes N information layers on a substrate (1), where N is an integer of 2 or more. Information is recorded/reproduced by irradiating each of the information layers (11, 12) with a laser beam (4). When the N information layers are referred to as a first information layer to an N-th information layer sequentially from the opposite side to a laser beam incident side, the L-th information layer included in the N information layers includes at least a recording layer (135) capable of undergoing a phase change through laser beam irradiation, a reflective layer (132), and a transmittance adjusting layer (131) in this order from the laser beam incident side, where L is an integer satisfying 2≦L≦N. The transmittance adjusting layer (131) contains Nb, oxygen (O), and at least one element M selected from Ti, Zr, Hf, Y, Cr, Zn, Ga, Co, Bi, In, Ta, and Ce. In the transmittance adjusting layer (131), the content of Nb is at least 2.9 atom %.
    • 本发明的信息记录介质在基板(1)上包括N个信息层,其中N是2以上的整数。 通过用激光束(4)照射每个信息层(11,12)来记录/再现信息。 当将N个信息层从与激光束入射侧的相对侧依次称为第N信息层的第一信息层时,包含在N个信息层中的第L信息层至少包括记录层 (135),其能够通过激光束照射进行相变,反射层(132)和透射率调节层(131),其中激光束入射侧依次为L,其中L为满足2 <= L < = N。 透光率调整层(131)含有Nb,氧(O)和选自Ti,Zr,Hf,Y,Cr,Zn,Ga,Co,Bi,In,Ta和Ce中的至少一种元素M. 在透射率调整层(131)中,Nb的含量为2.9原子%以上。
