Abstract
(EN)
A servo pattern recording method according to an embodiment of the present invention involves recording a servo pattern on a tape-like magnetic recording medium that is provided with a magnetic layer having multiple servo bands (at least five); the method includes selecting, from among the multiple servo bands, at least three first servo bands whereon a first servo pattern is to be recorded and at least two second servo bands whereon a second servo pattern, which is different from the first servo pattern, is to be recorded, and recording the first servo pattern and the second servo pattern on the first servo band and the second servo band respectively in phase with each other.

Selon un mode de réalisation, la présente invention concerne un procédé d'enregistrement de motif d'asservissement impliquant l'enregistrement d'un motif d'asservissement sur un support d'enregistrement magnétique de type bande qui est pourvu d'une couche magnétique comprenant de multiples bandes d'asservissement (au moins cinq). Le procédé comprend les étapes suivantes consistant à : sélectionner, parmi les multiples bandes d'asservissement, au moins trois premières bandes d'asservissement sur lesquelles un premier motif d'asservissement doit être enregistré et au moins deux secondes bandes d'asservissement sur lesquelles un second motif d'asservissement, qui est différent du premier motif d'asservissement, doit être enregistré, et enregistrer le premier motif d'asservissement et le second motif d'asservissement sur la première bande d'asservissement et la seconde bande d'asservissement respectivement en phase l'un par rapport à l'autre.
