    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： There is provided a layer-built chemical cell device, which comprises: a positive electrode including a current collecting material and an active material layer; a negative electrode including another current collecting material and another active material layer; an electrolyte introduced in a sealed space formed by fixing together the positive electrode and negative electrode; a separator layer interposed between the positive electrode and the negative electrode. The active material layer of either the positive electrode or the negative electrode is formed by laminating a plurality of active material sub-layers containing one or more active materials, such an active material layer being depositted on a current collecting material so as to form either the positive electrode or the negative electrode.
