Gnerally there is reduced output in mv and high frequency fall out as the head wears and on a pro recorder, a record is kept of it's alignment and a dbv record of frequency fallout as measured on a RMS AC voltmeter like a Gen Rad 1840 or an Eico 250 with an alignment tape. Also, there is a wear pattern on the face of the head where the tape has cut into the resin and case. It generally takes a tech who know what he is looking for. Sometimes if the wear pattern is irregular due to mis alignment and has not eaten in to the magnetic core stack of laminations and widened the gap, the head can be re-lapped (re-ground with a new hyperbolic face).
