- 3 Fm, and said thin film magnetic transducing element is
formed on said insulating film and has a thin film magnetic
circuit including a magnetic film and a coil film, wherein
said insulating film is formed between said electrically
conductive substrate and said magnetic film and allows an
equipotential to be formed therebetween because of its
thickness, and wherein said coil film is electrically
insulated by an organic insulating resinous film having an
insulation resistance sufficient to electrically insulate said
coil film in view of the thickness of said insulating film.
2. A thin film magnetic head which comprises:
a slider and a thin film transducing element, wherein
said slider has an electrically conductive substrate as its
major portion, and said thin film magnetic transducing element
comprises a magnetic film and a coil film, a surface of said
magnetic film being directly formed on said electrically
conductive substrate so as to form an equipotential
therebetween, and wherein said coil film is electrically
insulated by an organic insulating resinous film having an
insulation resistance sufficient to electrically insulate said
coil film in view of the absence of an insulating film between
said magnetic film and said electrically conductive substrate.
3. A thin film magnetic head which comprises:
a slider and a thin film magnetic transducing
element, wherein said slider comprises an electrically
conductive substrate as its major portion and an insulating
film formed on said electrically conductive substrate, a
thickness of said insulating film being in the range of 0.5 Fm
- 3 Fm, and said thin film magnetic transducing element
comprises a magnetic film and a coil film and its [sic, is]
formed on said insulating film so that at least a part of said
magnetic film is in direct contact with said electrically
conductive substrate through a hole formed in said insulating
film, wherein said insulating film is formed between said
electrically conductive substage [sic, substrate] and said
