GIMBAL SPRING FOR MAGNETIC HEAD

摘要

PURPOSE:To improve the reliability of a magnetic head by forming an insulating layer on the surface of a spring piece and forming a conductive film constituting lead wires for the magnetic head on the insulating layer. CONSTITUTION:A stainless steel sheet having 20-60mu thickness is used for the spring piece 2 and a polyimide resin is coated to, for example, about 10mu thickness on the surface of said sheet which is used as a substrate. The resin is then etched to the prescribed continuous shape extending from the base end part of the piece 2 to a holding part 2a along the edge part to form the insulating layer 9. Aluminum or the like is deposited by a vapor deposition method on the layer 9 and the deposited film is formed to a prescribed shape by a photolithographic technique. The stainless steel sheet is finally formed to the shape of a gimbal spring 8 by an etching method.
