    摘要： A write once read many type optical disc comprises a light transmissive substrate having a tracking groove formed therein, a light absorbing layer disposed on a surface of the substrate on which the tracking groove is formed, and a light reflection layer disposed on the light absorbing layer, wherein an RMI value defined by the following formula is not lower than 0.22: RMI value=(I.sub.l -I.sub.g)I.sub.o, wherein I.sub.l denotes an electric potential at a land portion, I.sub.g denotes an electric potential at a groove portion, and I.sub.o denotes an electric potential at a mirror surface portion.When the write once read many type optical disc is caused to have a structure as described above, there may be provided the write once read many type optical disc having a good playability, i.e., the optical disc wherein the TE level may be provided assuredly on the basis of a value obtained from one beam.

    摘要： An information recording medium comprising a pair of disk substrates at least one of which has an optical recording layer on one surface thereof, wherein the substrates are bonded to each other by using a silicone type adhesive, directly or by the medium of a spacer, so that the recording layer may be disposed inside of the substrates. Platinum is incorporated in the above-mentioned silicone type adhesive by using a platinum type crosslinking catalyst, without using the conventional benzoyl peroxide type crosslinking catalyst. Accordingly, there is provided the information recording medium excellent in mechanical strength, reliability and durability.
