Title: Magnetic head
Inventor: OTOMO MOICHI
IPC: G11B5/187
Filed: 1985-02-13
Abstract: PURPOSE:To increase the recording/reproducing efficiency and at the same time to reduce the inductance for each number of winding in order to attain the excellent characteristics for a magnetic head using a metallic magnetic material at a place near an action gap, by suppressing the increase of the core magnetic resistance and increasing the leakage magnetic resistance at a winding part. CONSTITUTION:The sectional area of a magnetic core part having high permeability is reduced down that of a metallic magnetic material 1 by using the nonmagnetic material to the cores 2 and 2' at a winding part. Thus the leakage magnetic resistance Rf is increased at the winding part. Here the increase of the magnetic resistance Rc of the core is suppressed by the metallic magnetic material of high permeability. Furthermore the nonmagnetic materials 4 and 4'are used to the magnetic core in a range from the tape rubbing surface through the winding part to increase the resistance Rf. This reduces the inductance. While the ferrite of high permeability is used to a rear core excluding the winding part. This suppresses the increase of the resistance Rc of the core as well as the decrease of the reproduction efficiency. As a result, the performance C/L<1/2> is improved more.
