Process for magnetically characterizing the registration layer of a magnetic information support

摘要

method for characterizing a magnetic medium information (tamb) consisting of a plurality of tracks each having a synchronization index ((ind).;according to the invention, the method is characterized in that:(1) we identify the synchronization index (ind), which makes it possible to initialize (pulse sequence (in) sequ2081, sequ2082, etc.) of the following sequence: 1) p, repeatable it first on the entire surface of the lead 3 is written on the surface of. can i (i + 1), + 2), (4) according to the sampling time (tn, tn + 1 is determined.with a fixed sampling period, a signal s according to the magnetization in each of the areas are read at these times (5) stores current values i and the signal.
