A buried servo magnetic recording system involves a moving head c magnetic recording system in which the head position is controlled by means of a prerecorded servo signal that resides in the same portion of the recording medium as the stored data. For continuous servoing from this servo signal, the system must be able to separate the servo signal from the recorded data. This is achieved with electronic filters, as indicated in Fig. 1.
