本発明は九とえば光デイスク媒体として用いられる情報
記憶媒体に関する。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to an information storage medium used, for example, as an optical disk medium.
光ディスク媒体は少なくともその片面側にレーザ光線な
どによる記録あるいは再生が可能である情報形成層を有
してなるが、この情報形成層としては無機膜のものと有
機膜のものとに大別される。An optical disk medium has an information forming layer on at least one side of the medium that can be recorded or reproduced using a laser beam, and this information forming layer is broadly classified into an inorganic film and an organic film. .
前記無機膜の情報形成層にはピット形成型、相変化型、
バブル形成型があシ、また、前記有機膜の情報形成層に
はピット形成型、分子構造変化型がある。このような種
々の機能膜は膜の生成法、材料の違いにより、反射率が
異なる。The information forming layer of the inorganic film may include pit forming type, phase change type,
The information forming layer of the organic film includes a bubble forming type, a pit forming type, and a molecular structure changing type. These various functional films have different reflectances depending on the film production method and material.
また、書き込まれた信号の極性の相違、すなわち、書込
まれた信号部の反射率が高くなる場合と、逆に低くなる
場合とがある。Further, there are cases where the polarity of the written signal is different, that is, the reflectance of the written signal portion becomes high and vice versa.
また、機能膜の相違により光源のノぐワーの閾値が異な
っ几りする。Furthermore, the threshold value of the light source's output varies depending on the difference in the functional film.
このため、従来においては、種々の光デイスク媒体に対
