The automatic adjustment looks at phase difference between the
channels and drives a motor which adjusts the head.

In order to do this, though, it has two or more channels for each channel
on the tape, so it can look at two halves of one track to determine the
angular error. This makes the automatic azimuth machines electronically
a good bit more complex.
