Abstract: A method for forming metrology structures on a wafer on which magnetic transducers are being fabricated is disclosed. The metrology structures have a measurable electrical resistance which is an accurate surrogate for a physical dimension of a structure of the magnetic transducer, such as a pole piece tip. The metrology structure is preferably a resistor with pads usable with a four point probe.

Control structures with unmilled pads of resistive material are formed along with the metrology structures to provide the sheet resistance of the pads prior to milling.

In addition, as a result of the outside radial position of the main segment of the unbalanced body, the unbalanced mass can easily be changed by means of additional masses which can be inserted into the segment and removed from it.
