Abstract: A prepaid card processing device for processing a prepaid card has a memory for storing information relating to an account, e.g., of money, and a printing portion on which the information is recorded. A prepaid card processing device has a reading portion for reading the information stored in the card memory; an input portion for inputting a charge amount of money for a transaction; a defrayal information processing portion for calculating the balance amount based on the charge amount inputted by the input portion and for preparing the defrayal information relating to the balance amount and the charge amount; a printing portion for printing defrayal information on the card; and a decision control portion for deciding whether or not the defrayal information is to be printed on the card by the printing portion. When the decision control portion decides that printing need not be performed, no printing on the card occurs. Thereby, the printing space on the card can be effectively utilized.
Abstract: A magneto-optical recording medium comprises a dielectric film disposed on a substrate and formed, for example, of silicon nitride, of for example, 65 nm thickness, a magnetic film disposed on the dielectric film, and formed, for example, of, rare earth-transistion metal alloy thin film, of, for example, 35 thickness, and a reflective film disposed on the magnetic film, and formed of titanium nitride, by, for example, sputtering.
