Abstract
본 발명의 목적은 메모리부착 카세트가 VCR에 적적하게 장전되어 있는지 아닌지를 검출할 수 있도록 하는 동시에 메모리부착 카세트의 소정의 정보를 VCR의 종류에 관계없이 독출하도록 한다. 또 메모리부착 카세트에서 독출한 데이터에 의거해서 카세트의 용도나 카세트가 신품인지 아닌지를 판별할 수 있도록 한다. 그리고 또 아날로그 VCR에 이용되는 테이프의 테이프정보를 독출할 수 있도록 하는데 있다.
그 구성은 메모리부착 카세트내에 설치된 메모리는 EEPROM과 플래시메모리로 된다. 또 메모리의 APM, BCID 및 소정어드레스의 데이터를 미리 고정한 수치로 하여 놓는다. 또한 메모리부착 카세트(61)의 단자(64a, 64b 및 64c)가 VCR측의 단자(65a, 65b 및 65c)에 접속된다. 이들의 단자를 거쳐서 메모리부착 카세트의 전압레벨이 레벨검출부(70a, 70b 및 70c)에서 검출된다. 레벨검출부(70a, 70b 및 70c)의 각각의 출력은 제어기(10)에 공급된다.
