ABSTRACT:
A track following positioning system including filtered average servo demodulators for maintaining the position of a magnetic tape head in alignment with tracks of data stored in magnetic medium. A servo head tracks a centerline in a servo written region of the magnetic medium and generates servo head signals corresponding to the displacement of the servo head from the centerline. A filtered average servo demodulator detects the servo head signals and generates servo error signals for realigning the tape head with respect to the magnetic medium in response thereto. To generate servo error signals, the filtered average servo demodulator peak detects and averages the rectified and filtered output signals and then subtracts a proportion of the peak detected signals from the average detected signals.
