Abstract

PURPOSE:To obtain the magnetic head excellent in magnetic efficiency, by forming a pair of multiwinding coils having common conductor on the magnetic board, forming the magnetic column in the magnetic flux generating window of each coil, and simultaneously generating the magnetic flux of different direction in both magnetic columns. CONSTITUTION:The first, second ends and the intermediate part are respectively connected to the first terminal 3, the second terminal 4 and the intermediate terminal 5, and the exciting coil 2 forming the second magnetic flux generating window and the second one between the first terminal 3 and the intermediate terminal 5 and between the second terminal 4 and the intermediate terminal 5, is provided on the magnetic board 1. Further, the first and the second magnetic columns 6, 7 are formed at the first and the second magnetic flux generating windows of the exciting coil 2, and the columns 6, 7 are provided with the magnetic plates 8 and 9 having the gap G at a part of the magnetic flux path and connecting both ends to the columns 6, 7 magnetically, and the magnetic flux of different direction is generated in the columns 6, 7 by supplying a current between the inter mediate terminal 5 and the first terminal 3 or the second terminal 4, allowing to obtain the objective magnetic head.
