PURPOSE:To easily adjust the writing property of a closure track and a writing track without lowering reproducing sensitivity by winding a short coil to a I core of a magnetic head for computer. CONSTITUTION:A magnetic gap is formed with holding the both sides of a I core 4 in which a concave part is formed at a tip top center part with a recording core 2 and a reproducing core 3 which are wound respectively, in the tip top center part of the reproducing core 3, a projection part is engaged to the concave part of the I core 4. A short coil 13 is wound to the one part of the I core 4 like this, a resistance value is adjusted by adjusting the winding number of the short coil 13 properly, the writing property of a closure track 21 and a reading track 22 is corresponded. Thus, since it is unnecessary to adjust the winding number of a coil 12 of the reproducing core 3, the writing property of the closure track 21 and the reading track 22 can be coincided without lowering reproducing sensitivity. |
