Abstract:
1. A method for accurately machining a magnetic tape head comprising: depositing a plurality of tape head elements on a substrate; depositing a resistive transverse stripe on the substrate adjacent to the plurality of tape head elements with a height exceeding that of the plurality of tape head elements and a notch with a height corresponding to a target height limit of the plurality of tape head elements; connecting a first lead to the resistive transverse stripe; connecting a second lead to the resistive transverse stripe spaced apart from the first lead with the notch in between the first and second leads; measuring resistance of the resistive transverse stripe from the first and second leads; machining the resistive transverse stripe and the plurality of tape head elements by removing material from the height of the resistive transverse stripe and the plurality of tape head elements; and discontinuing the machining upon a dramatic increase in the resistance of the resistive transverse stripe indicating that the machining has reached the notch.
