THIN FILM HEAD FOR VERTICAL MAGNETIC RECORDING AND REPRODUCING

摘要

PURPOSE:To remove a waving phenomenon of a recording density independent curve and to improve recording and reproducing characteristics by constituting a main magnetic pole so as not to be in parallel with an auxiliary magnetic pole. CONSTITUTION:A V-shaped groove is formed on the auxiliary magnetic pole plate to be also used as a substrate and an auxiliary magnetic pole 22 is formed by embedding glass or the like and smoothing the surface. The auxiliary magnetic pole 22 is not made parallel with the main magnetic pole 26 through an inorganic insulating layer 23 provided with a conductive coil 24 because of said bevel shape, so that the waving phenomenon of the recording density independent curve of a recording density reproducing output is removed and the recording and reproducing characteristics of a vertical magnetic recording/reproducing thin film head are improved.
