Appeal No. 97-1166
Application 08/198,848
after final rejection was filed on October 30, 1995 and was
entered by the examiner. This amendment amended claims 1, 11 and
19, and cancelled claims 21 and 22. Therefore, this appeal is
directed to the rejection of claims 1-20.
The invention pertains to a magnetoresistive (MR) sensor
for reading information from the track of a magnetic storage
medium. Specifically, a giant MR element is provided which has
three electrical contacts spatially positioned along the
direction of the track. A first variable resistance current path
is established between the first and second contacts, and a
second variable resistance current path is established between
the first and third contacts. Magnetic information recorded on
the track passes the electrical contacts at different times and
causes the variable resistance of the current paths to change in
a measurable way.
Representative claim 1 is reproduced as follows:
1. A sensor for reading information from one of a
plurality of longitudinal tracks of a magnetic storage medium
moving underneath the sensor, the sensor comprising:
a slider having a side rail, the side rail having a
bottom surface, wherein the slider is arranged to position the
bottom surface of the side rail adjacent a first track of the
plurality of longitudinal tracks;
a giant magnetoresistive element positioned on the bottom
surface of the side rail;
