Abstract
A system for the reading of a multitrack recording medium comprising a device enabling the reading, on the width of each track, of a number n of information samples. The system includes a filter enabling the making of several combinations of several samples of a track, these combinations differing from one another by a shift equal to one or more samples; a sub-sampling circuit that chooses a determined combination from among the different combinations of a track under the control of a position predictor; a positional error computation circuit computing the positional error of the chosen combination and giving an error correction signal to the position predictor.
