Abstract

PURPOSE:To prevent the efficiency of a head from being lowered, by forming a conductive layer with higher aspect ratio more than a specified value near a magnetic gap. CONSTITUTION:A magnetic layer is formed on a substrate 13 and a lower magnetic layer 14 is provided by leaving a magnetic layer only for a specified part through patterning. On the layer 14, an Al2O3 layer 19 and a conductor layer (Al- Cu alloy and the like) 16 are formed and a longitudinal conductor layer (hereinafter, called a conductor) 17 is formed through etching. Next, on the conductor 17, a resin (such as polyamide) 18 is coatd to form a magnetic layer 20 after forming an Al2O3 layer 19 on the resin by leaving required part through etching. Next, the layer 20 is etched and a gap 20 is formed by cutting off the tip X-X'. Thus, as shown in figures, the ratio of the height (h) to a width (l1) of the conductor 17, i.e., aspect ratio h/l1 is taken more then 1. Further, the ratio of the height (h) and width (l2) between the conductors 17, h/l2 is taken as more than 1. Thus, a head with thin type and short yoke length and high efficiency can be obtained.
