Appeal No. 2001-2262
Application 09/006,014
Representative claim 11 is reproduced as follows:
11. A multi-channel magnetic head having a head face which
extends in a first direction and in a second direction transverse
to the first direction, for scanning a record carrier which is
relatively movable with respect to the magnetic head in the first
direction,
comprising a structure of layers which extend respectively
substantially in the second direction and in a third direction
transverse to the first and second directions, said layers being
disposed one on top of the other as viewed in the first
direction,
said structure including a plurality of magnetoresistive
sensors, each of said magnetoresistive sensors comprising a
magnetoresistive measuring element, a first magnetic element and
a second magnetic element respectively,
said magnetoresistive measuring elements being arranged such
that, viewed in the second direction, adjacent magnetoresistive
sensors are distinguishable; and, viewed in the first direction,
the magnetic elements are opposite each other, at least the
respective first magnetic elements extending as far as the head
face,
characterized in that both magnetic elements of each of at
least two adjacent magnetoresistive sensors are electrically
conducting and have respective electric connection faces, the
respective magnetoresistive measuring element being electrically
arranged in series between the respective two magnetic elements
for passing a measuring current through the measuring element
substantially in the third direction.
