PROBLEM TO BE SOLVED: To discriminate the use of a cassette and whether the cassette is new, based on read data from a cassette with memory. SOLUTION: A memory provided in the cassette with memory comprises an EEPROM and a flash memory. Moreover, the data of memories APM, BCID, and a predetermined address are set to a value fixed in advance. Further, terminals 64a, 64b, 64c of the cassette with memory 61 are connected to terminals 65a, 65b, 65c on a VCR side. Voltage levels of the cassette with memory are detected via these terminals at level detecting sections 70a, 70b, 70c. Respective outputs of the level detecting sections 70a, 70b, 70c are applied to a controller 10. COPYRIGHT: (C)2004,JPO&NCIPI
