IPC: G11B7/24035
Filed: 1990-06-21
Abstract: PURPOSE:To provide an optical record medium capable of additional recording and compatible with drives for compact disk and laser disk by depositing refractory inorganic salt by irradiating a separation layer with recording light. CONSTITUTION:Before recording, a layer 400 containing salt with inorganic cation which generates refractory inorganic salt by mixing and organic anion such as carboxylic acid anion and a layer 200 containing salt with inorganic anion and organic cation such as 4th class ammonium cation are separated by a separation layer 300 containing a compound having a photo absorption in recording light. In this state, a substantial education of the refractory inorganic salt does not occur. A regenerative light will not be diffused and it is considered that it has a high reflection factor. When the record film is irradiated with the recording light, the reflection factor decreases so that a record signal can be obtained. That is, when the recording light is irradiated, the separation layer is heated and a melting occurs, so that a part of the anion layer and cation layer is mixed and interchanged so as to finally form the refractory inorganic salt in the film and the regenerative light will be diffused.
