摘要

A magnetic tape video cassette has a built-in memory chip (6) that contains identification data and information relating to the type of recording. Access to the memory when the cassette is loaded into the recorder is provided by contacts (5) on the chip that connect with contacts on the surface of the cassette. The cassette surface contacts are provided by the embossed letters indicating the type of cassette, e.g. V.H.S. The letters are formed on one side of the cassette wall with the chip located in a recess on the other side. ADVANTAGE - Uses inscription symbols as contacts for built-in memory.
