Videotape recorders intended for the consumer market began to appear about 1964. Since then, many new developments have appeared in the recording of the chroma signal, in the increase of recording density, and in the mechanism of recorders. These developments have brought about the introduction of cassettes to house the videotapes. Representative of such a trend is the U-matic videocassette, the superior performance of which has opened up many technical applications. Recently, the U-matic system has begun to be applied to broadcast uses, drawing worldwide attention.
