The invention
The invention is a thin film magnetic head. Four
different embodiments are disclosed. Referring to the first
embodiment (Figs. 1 and 2), the slider 1 includes an
electrically conductive substrate 101 and an insulating film
102 formed thereon (hereinafter referred to as a substrate-
insulating film to distinguish it from other insulating films)
(Spec. at 6, lines 1-4). Figure 2 and the specification (at
6, lines 4-6) give the thickness of the substrate-insulating
film 102 as "0.5-3Fm" and "in the range of 0.5 Fm - 3 Fm,"
respectively, which is stated to be less than the 10 Fm or
more thickness this layer has in conventional thin film
magnetic heads (Spec. at 8, line 24 to p. 9, line 8).
Magnetic film transducing element 2 includes a lower magnetic
film 21, upper magnetic film 22, and coil films 23 (Spec. at
6, lines 18-20). The lower magnetic layer 21 is formed on
