Appeal No. 98-0600
Application 08/541,441
Claims 1, 2, and 4-7 stand rejected under 35 U.S.C. § 103
as being unpatentable over Kira.
The Invention
The claimed invention is directed to a giant
magnetoresistive transducer having an air bearing surface,
including a giant magnetoresistive sensor. The sensor has a
sensing surface and side surfaces and is recessed at a
distance S from the air bearing surface for defining a gap
between the sensor and the bearing surface. Magnetic shield
members are spaced from the side surfaces of the sensor and
are separated from each other by a distance G. The distance S
is less than half the distance G. A dielectric layer is
disposed within the gap.
Claim 1 is the only independent claim and reads as
follows:
1. A giant magnetoresistive transducer for reading
data signals recorded on a surface of a magnetic
medium, said transducer having an air bearing
surface comprising:
a giant magnetoresistive sensor having a sensing
surface and side surfaces, said sensor being
recessed at a distance S from said air bearing
surface to define a gap between said sensor and said
air bearing surface;
