Abstract
PURPOSE: To make it possible to record the head positioning signal without complication of the loading mechanism of a magnetic tape, by constituting a circuit so that the FE head can perform the full-width signal erasing function and the head positioning signal recording function.
CONSTITUTION: One output terminal of high frequency oscillating circuit 4 is connected to the first terminal of driving coil 3 of FE head 2, and a high frequency current for signal erasing is output to driving coil 3, and the series connection material consisting of capacitor 6 and unidirectional element 7 is connected in series between the first and the second terminals of driving coil 3 so that capacitor 6 may be in the side of the second terminal of driving coil 3, and the first switching element 8 is provided between the earth and the connection point of capacitor 6 and unidirectional element 7, and the second switching element 10 is provided between the second terminal of the driving coil and the earth, thus constituting the driving circuit.
