Abstract
PURPOSE: To improve junction strength of a back gap part, which is made equal to all of the core width, and reduce the magntic resistance, by providing grooves previously for slicing and by causing melted glass to permeate from these grooves.
CONSTITUTION: After a prescribed nonmagnetic film is formed on the surface of wafer 1, the first groove 12 to prescribe the track width is formed from left and right ends 5 and 5' toward the inside. Next, the second groove 16 linking groove 12 formed according to the future cutter space. Next, winding grooves 19 and 19' and glass insertion grooves 20, 20' and 21 are cut bisymmetrically in the direction orthogonal to the extending direction of grooves 12 and 16. Next, a pair of wafers are matched to each other with their process faces opposite to each other and with a space corresponding to the gap length and are caused to adhere to each other by glass melting. Next, this block is divided into two along glass insertion groobe 20, and after that, it is sliced along the second groove.
