A thin film, magnetoresistive sensor for magnetic recording is described. Unlike conventional devices, the magnetic thin film is deposited onto the walls of a "V"-etched substrate rather than on a flat substrate. Then lapping the substrate from the "bottom", an air bearing surface may be formed without the need to bond a supporting piece. Also to be gained is minimization of wear to the magnetoresistive film during abrasion with recording media since the amount of the film exposed is reduced.
