Abstract
A method for manufacturing a magnetic core for use in data transducing, characterized by having the depth of the shallower flux gap face precisely equal to a predetermined value. The method involves machining a notch in the flux gap face of one element at a precise distance from a reference surface before bonding of the two elements of the core together. The transducing surface can then be machined after assembly to an exact distance from the reference surface to automatically determine the desired flux gap depth.
