Abstract
For the selection of the columns of elementary heads of a multitrack recording head, the method makes use of a bipolar pulse with amplitudes +2I/3 and -2I/3. For the selection of lines of elementary heads, it makes use of pulses with an amplitude of +I/3 or -I/3. And for the non-selected lines, it uses a bipolar pulse that is in phase opposition with respect to the column selection pulse and has amplitudes of +I/3 and -I/3.
