  • Magnetic head recording multitrack servo patterns
    Patent number: 4996609
    Abstract: A novel apparatus and method is described for recording a pattern of track positioning servo signals at select locations of a magnetic tape for use in aligning a single track read head with each of the tracks defined by the signal pattern. The pattern is provided by recording two different signals with two write heads so that the signals are recorded as alternating strips. The differences between the two signals are then used to define the each track center.
