摘要

The read head arrangement comprises n first read heads (ha.1, ..., ha.n) and n second read heads (hb.1, ..., hb.n) of the magnetoresistance type, n transistors (Tr1, ..., Trn) and switching means (S), where n is an integer greater than two. The first main electrode (collector) of a transistor (Tri) is coupled to an i-th output (Ui) of the arrangement. The second main electrode (emitter) of the transistor (Tri) is coupled to a first terminal (t1) of a first read head (ha.i) and a second read head (hb.i). The second terminal (t2) of the first read head (ha.1) is coupled to a first terminal (a) of the switching means (S). The second terminal (t2) of the second read head (hb.i) is coupled to a second terminal (b) of the switching means (S), of which a third terminal (c) is coupled to a point of constant potential (earth), while i ranges from 1 to n.
