ELECTRICAL-EFFECT DATA RECORDING MEDIUMS THAT INCLUDES A LOCALIZED ELECTRICAL CONDUCTION LAYER

摘要

An electrical-effect data recording medium is preferably formed by a successive stacking of a protective layer, a localized electrical conduction layer, a recording layer, a thin layer forming an electrode and a substrate. The localized electrical conduction layer is formed by a low electrical conductivity material, in which inclusions having a higher electrical conductivity than that of the material are dispersed. The inclusions can be oblong or spherical in shape and the material presents a non-linear electrical conduction.
