An integrated, multitrack, magnetic reading head in which a Hall effect or magneto-resistive material strip is deposited on a silicon substrate. The voltages produced in this strip are sampled by a group of amplifiers for the parallel-charging of a charge-coupled device, which is then read in series to obtain the output signal. Lateral tracks energize circuits making it possible by means of two resistive lines and a system of comparators to open the input gates of the charge-coupled device in order to correct the skew of the reading head. |
