摘要： A magnetic head (100,710) for reproducing a signal recorded on a recording medium, includes a substrate (101), a magnetic head core (130) provided on the substrate, having a magnetic gap (120), and a magnetoresistance device (150) provided on the magnetic head core. The magnetic head core is provided in such a manner that a thickness direction (102) of the magnetic head core around the magnetic gap is substantially the same as a track width direction of the recording medium.

摘要： Multi-channel magnetic head having a high channel density, provided with a head face (1) which extends in a first direction (I) in which a record carrier is relatively movable with respect to said magnetic head, and in a second direction (II) transverse to the first direction. The magnetic head has a structure of layers which, viewed in the first direction, are situated one on top of the other and extend substantially in the second direction and in a third direction (III) transverse to the first and the second direction. Viewed in the second direction, adjacent magnetoresistive sensors (S1, S2, S3) are distinguishable in the structure, each comprising a magnetoresistive measuring element (5), a first magnetic element (7) and a second magnetic element (9). The magnetic elements of adjacent sensors are electrically conducting and have electric connection faces (70a, 9a), while the measuring element in each sensor is electrically arranged in series between the first and the second magnetic element for passing a measuring current (i) through the measuring element substantially in the third direction.
