PURPOSE:To form a highly efficient compact magnetic head by reducing winding number of each 1st coil part, making an area at the scan head part side of a substrate small and increasing an area at the side of the non-scan head part of the substrate so as to raise the winding number of each 2nd coil part. CONSTITUTION:The winding number of the 1st coil part 19 in each scan head part 13 disposed in parallel is lessened, and the area at the bottom side of the substrate 12 where the 1st oil part 19 is disposed and formed, that is, the area at the side of each scan head part 13, is reduced. Thus each scan head part 13 can be made smaller corresponding to the width W of a magnetic tape 11 as a magnetic memory medium. On the other hand, the area at the upper side of the substrate 12, that is, the area at the side of non-scan head part 13 is made larger, and the winding number of a secondary side coil part 26 in the 2nd coil part 27 is raised, whereby an input of a secondary inducing voltage upsilon2 more than the prescribed voltage value can be possible at a signal input part 22 as a signal exchange part. Thus the voltage value upsilon2 higher than a voltage value upsilon1 outputted in the 1st coil part 19 is inputted to a signal input part 33. |
