INFORMATION RECORDING AND REPLAYING APPARATUS

摘要

An information recording and replaying apparatus comprising a recording layer including a typical element as a diffusible ion, movement of which causes to record two or more states having different electrical resistances, and an electrode layer disposed on one end of the recording layer for applying a voltage or current to the recording layer. The electrode layer, in a region adjacent to the recording layer, includes the typical element in a concentration higher than that in the recording layer.
