Abstract
Multi-channel magnetic head having a high channel density, provided with a head face ( ) 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 (S , S , S ) are distinguishable in the structure, each comprising a magnetoresistive measuring element ( ), a first magnetic element ( ) and a second magnetic element ( ). The magnetic elements of adjacent sensors are electrically conducting and have electric connection faces ( ), 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.
