Abstract
The magnetizing control signal MAGCH becomes the high level if there is no magnetic reversal during a period of a predetermined number of clocks and becomes the low level if there is a magnetic reversal. If the magnetizing control signal MAGCH is the low level, the high voltage VH is applied to the center tap of the bifilar winding of the magnetic head via the transistor . The transistors or the transistors are turned on in accordance with the write data signal DATA, *DATA. Therefore, the magnetizing current flows through one of the winding elements and . If the magnetizing control signal MAGCH is the high level, the transistors or the transistors are turned on in accordance with the write data signal DATA, *DATA. Therefore, the magnetizing current flows from the low voltage VL to both the winding elements and
