    摘要： A method of making a flat magnetic structure having coils thereon, said structure including magnetic read/write heads using a flat substrate that has at least one side made of a magnetic material, said method including the steps of:initial machining of the magnetic side of the substrate to form supporting means for conducting wires, which forms said coils, and to demarcate future magnetic poles of said magnetic read/write heads; then depositing, on either side or both sides of the substrate, connecting pins at a rate of two pins per said coil; then positioning the conducting wires on said supporting means to form the coils; then connecting the ends of the conducting wires of each coil to the corresponding connecting pins; then coating the machined magnetic side with an insulating material; and then machining and polishing the coated side until the magnetic poles are exposed.

    摘要： The invention concerns a method for the detection of the end of grinding of at least one thin layer magnetic head, the head comprising, at the stage of implementation of said method, an active face, formed by two magnetic poles (1, 2) separated by a gap (4). The method comprises the following steps:deposition of a conductive layer (7) on the entire active face (3)etching of the active face coated with said conductive layer;deposition of a layer of dielectric material (8) on the etched active face;grinding of the active face starting from the face that is free of the layer of dielectric material (8) until total removal of that part of the conductive layer (7) located above the gap (4), this removal being detected by the sudden variation in resistivity between the two magnetic poles (1, 2).
