Appeal No. 96-1707
Application 08/221,999
at a front end portion providing a first front gap, in use to be in contact with a
magnetic recording medium,
for picking up magnetic flux of the magnetic recording medium; and wherein
a second lower yoke formed on a surface of said substrate, opposing to
said first lower yoke with a third interlayer insulating film interposed and extending
at a distance behind said first lower yoke with a surface which is in contact in use
with and sliding relative to a magnetic recording medium at a front end,
a fourth interlayer insulating layer formed to have approximately trapezoidal
cross section at a region behind said first lower yoke on an upper surface of said
third interlayer insulating layer,
a second electromagnetic transducing element provided on the fourth
interlayer insulating layer,
a fifth interlayer insulating layer formed on the second electromagnetic
transducing element and
a second upper yoke of a magnetic thin film formed along an upper surface
of the fifth interlayer insulating layer,
said first upper yoke and said second upper yoke being formed of the same
layer of magnetic thin film; and wherein
said second yoke magnetic head includes an upper yoke provided by
combining magnetically said first lower yoke and said second upper yoke, said first
lower yoke and said second lower yoke opposing with each other with said
third interlayer insulating layer interposed as a gap layer at a front end serving as a
surface which in use is in contact with and sliding relative to a magnetic recording
medium,
