摘要

Process of writing and reading of a magnetic track, in particular for the positional servo-control of the magnetic heads, this strip carrying to this end of the transitions of states, such that their magnetic reading provides pulses whose sign is representative of the direction of the transition, characterized in that it is recorded in the interval between two transitions 14 of the same direction of the signals 161, 162, such that their reading does not occur, a transition of the opposite direction, so that the transitions of the magnetization appear in the same direction. & br / the invention also relates to a magnetic support allowing îoeuvre of this process, as well as a process for the positional servo-control of the magnetic heads using îoeuvre such a support. & br / (see appended drawing in bopi) & br / & & br /
