Abstract
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.
