ABSTRACT:
A method for adjusting output signal levels from a magnetic bubble detector. Portions of the chevron stacks located adjacent to either the detector element or dummy element are selectively removed. This removal changes the magnetic field at either one of these elements, thereby adjusting the detector output. This removal may be performed with laser trimming techniques or by etching.
