PURPOSE:To avoid such a case that the signals recorded newly on a track are attenuated or become incomplete by using an erasion current switching means to switch the erasion current to be supplied to a flying erasion head in response to the detecting result of a tape type detecting means. CONSTITUTION:An amplifier 8 of variable amplification degrees amplifies the output of an oscillator 7 and supplies an erasion current to a flying erasion head FEH. A tape type detecting circuit 9 decides whether a video tape is equal to MP or ME and switches the amplification degree of the amplifier 8 according to the MP or ME. That is, the amplification degree of the amplifier 8 is increased with MP and decreased with ME respectively. As a result, the amplitude of said erasion current is large with MP and small with ME. Then, the amplitude most suitable to erasion of an MP video tape is secured with MP; while the amplitude most suitable to erasion of an ME video tape is obtained with ME respectively.
