Provided are a method, servo channel, and tape drive for recovering servo information from a synchronous servo channel. The plurality of circuit traces can each be coupled to a pair of circuit pads, and the circuit traces can be formed on an upper side of the base layer. The cabin further comprises at least one rectilinear ramp linking the first zone of the first deck to the second zone of the first deck, and at least one rectilinear ramp linking the first zone of the first deck to the second deck. Pressing on a cut row or column is basically determined by calculating the barycenters of \u2018virtual\u2019 hollows in the reception voltages corresponding to this cut row or column.
