Abstract
PURPOSE: To enable efficient recording on the magnetic tape with high coercive force, by forming the track width of recording gap greater than that of reproduction in the magnetic head, and winding the reproduction cancellation winding on the C shaped core forming the recording winding.
CONSTITUTION: The windings 17, 18 are provided for each of a pair of the C shaped cores 15, 16 and the gaps 20, 21 are formed. In such a magnetic head, the center core 12 is clipped with the C shaped cores 15, 16, and the reproduction gap 21 and the recording gap 20 are formed parallelly with the gap member. Further, the track width 8 of the recording gap 20 is formed greater than the track width 9 of the recording gap 21, the reproduction cancellation winding 22 is wound on the C shaped core 15 forming the recording winding 17, and the reproduction cancellation winding 22 is electrically connected to the reproduction winding 18.
