Abstract
A demagnetizing circuit of a home use video tape recorder is controlled by using means such as a control by a microcomputer or the like so as to execute a demagnetizing operation in a desired tape position interval. Further, by properly controlling an onscreen-display on a monitor display screen or a display on a VTR display tube, the operating efficiency is further improved.
