Abstract
PURPOSE:To shorten the required time of a process and to improve yield by disposing a lower magnetic material of the (n+1)th layer to the space generated between the head elements of the n-th layer and forming the lower magnetic material of the n-th layer and the upper magnetic material of the (n+1)th layer by a common forming process. CONSTITUTION:The lower magnetic material 4 of the head elements B1, B2 of the 2nd layer of, for example, a thin film head on a head sliding surface is so formed as to enter the space between the head elements A1, A2, A3 of the 1st layer and the lower magnetic material 4 of the head elements B1, B2 of the 2nd layer is formed simultaneously at the time of the process for forming the upper lower magnetic material 5 of the heads A1-A3 of the 1st layer. The result similar to the result when the process for forming the lower magnetic material 4 of the 2nd layer is eliminated is thereby substantially obtd. The required time of the process is thus shortened and the yield is improved.
