Assuming:

The tape moves along the X pos axis

The guides pull the tape to contact the heads in the Z pos axis

The Y pos axis is the mounting screw connecting the head to the block

Which plane is azimuth?

It is quite clear that errors in the XY Plane(Yaw) or YZ plane will
cause a 1/4 track tape to play tracks it shouldn't .Especially the XY
plane where height errors do not come into play

What are the results of errors in the XZ(pitch) plane? I.E. the head
is higher or lower on the left as on the right but there is no yaw (XY
error)

Any CNC programmers out there :-)
