ers on one side of ba material is prepared by tin vapor deposited layer having specified purity and thickness respectively. CONSTITUTION:The heat-nsitive recordable magnetic card is prepared by laminating contrast giving layer 4, first heat-nsitive layer 6, thin metal layer 8, cond heat-nsitive layer 10 and protective layer 12to one another in the order named. In this ca, the thin metal layer 8 is made of tin
