When the introduction says "between a reference plane and a point," does it really mean "between a reference plane, a point, and an observer"? There can be an angle between two lines, between a plane and a line, but not between a plane and just one point.
"For magnetic tape drives, azimuth refers to the angle between the tape head(s) and the tape medium."
Someone who knows should specify whether this is the transverse or longitudinal direction on the tape medium. I assume it is probably the former, as the gaps in the magnetic heads for audio tape are transverse to tape transport, or nearly so, and a small azimuthal angle would be more convenient. I am less clear about the spinning helical system for videotape.

"In navigation, the reference plane is typically true north and is considered 0° azimuth." Don't understand what plane is intended. I think true north is considered a vector. The plane traditionally defined by a vector is the one "normal" to the vector. Is this the correct reference plane?
