发明名称 INFORMATION RECORDING MEDIUM
摘要 PURPOSE:To extend the life of information and to improve weather resistance and an SN ratio by forming a recording trace consisting of a light recursive reflection part and a light non-recursive reflection part formed by selective thermal deformation corresponding to information recorded on a thermal deformation member consisting of a light recursive reflector or a light recursive reflector material. CONSTITUTION:The recording trace consisting of the light recursive reflecting part RR and a light non-recursive reflecting par rb due to selective thermal deformation corresponding to information recorded on the thermal deformation member consisting of the light recursive reflector RR or the RR materialis formed. Thereby, information can be recorded and the recorded information can be reproduced by irradiating the trace with light. Consequently, the life of the recorded information is long, the weather resistance and the SN ratio can e improved, the quality of the recorded information can be prevented from being deteriorated or erased due to transfer or magnetization, and the reading of the recorded information can be attained also from a distance position. Thus, the information recording medium capable of simply and easily recording and reproducing information can be obtained.
