  • Method and apparatus for the determination of azimuth error
    Patent number: 5552944
    Abstract: Azimuth error between a write head (16) and a read head (34) is determined by passing a multi-track tape (2) past the write head (16) and subsequently the read head (34). The signals written by the write head (16) and read by the read head (34) are analysed to determine the timing error (38) between best-match time-delayed portions (20-28) of these signals. This timing error (38) is indicative of the azimuth error.
