摘要: Undesirable interference beat patterns in the displayed video signals produced by a magnetic record/reproduce head are substantially eliminated appropriately changing amplitude of writing current to synchronism with polarity reversal establish ratio which will result uniform spacing between zero crossovers voltage output recording system.
