A method for fabricating a write-after-read magnetic head assembly employs rectangular wafers sliced from a block of abrasion-resistive material. The block is prepared, prior to slicing, with pairs of opposed slots extending inwardly from anterior and posterior surfaces. The slots are adapted to include inserts of magnetically soft material. The inserts at the anterior surface also are of high cost abrasion-resistive materials necessary for digital recording systems but represent a relatively tiny amount of such materials. Pairs of wafers are juxtaposed in a manner to form a core equivalent structure and two such wafer pairs are mounted in an assembly which defines write after read heads for two tracks in a manner to preserve azimuth and avoid crossfeed.
