Application No. 08/391,472
except in an area adjacent a track portion of a magnetic head
core bonded to a side surface of one of the slider rails.
Claim 22 is the only independent claim on appeal, and it
reads as follows:
22. A floating magnetic head comprising:
a substantially rectangular slider having a top
surface and a bottom surface, the slider made of a
non- magnetic substance, and having a first end defining
a leading end and a second end defining a trailing
end, the slider being provided with a groove on an
outside surface of the slider, wherein the groove extends
from a side surface toward the second end such that the
groove gradually increases in depth from the side
surface towards the second end and forms an opening at the
second end, the side surface located between the first
end and the second end and between the top surface and the
bottom surface;
rails provided on an air-bearing side of the slider
that faces a recording medium to produce a floating
force;
a magnetic head core bonded to the side surface of
the slider external to the rails by a glass bonding layer
between them, the magnetic head core having an inclined
face on a side opposite to the bonding side, the magnetic
head core having a track portion and a read/write gap and
having first and second legs, the second leg being located
at the second end of the slider without protruding from the
second end such that the first leg is located between the
second leg and the first end of the slider, the track
portion of the magnetic head core being attached externally
outside of the rails by bonding; and
a coil wound around the second leg, the coil being
at least partially in the groove, wherein the edges
