METHOD FOR COLLECTIVE PRODUCTION OF MAGNETIC HEADS WITH ROUNDED BEARING SURFACE |
摘要 |
A process for collectively making integrated magnetic heads with a bearing surface obtained by photolithography. According to the process, on a wafer is deposited a plurality of heads, a mask defining the profile of the bearing surfaces and the wafer is collectively engraved in the vicinity of the pole pieces of the heads. Such a process may find particular application to the making of magnetic heads. |
