ABSTRACT:
A magnetic head device is disclosed which comprises: a head tip including a pair of cores which are confronted with each other in such a manner that the cores are sufficiently spaced away from each other with a magnetic gap fored at one end; a bridge core bridging the pair of cores to allow a magnetic flux to flow out of one of the pair of cores and flow in the other core; and a coil placed in the path of the magnetic flux.
