摘要： Provided is a smear-removing method that can remove smear of a manufactured thin-film magnetic head. The method is performed to a thin-film magnetic head including an MR effect element for reading data having two electrode layers sandwiching an MR effect multilayer as a magneto-sensitive portion therebetween. The method comprises the step of applying a stress voltage less than a breaking voltage of the MR effect element between the two electrode layers to burn off smear. In the method, it is preferable that the stress voltage is applied while an electric resistance or an output voltage of the MR effect element is measured, and the stress voltage is increased until the value of the electric resistance or the output voltage reaches an upper limit specified value specified from a value of an electric resistance or an output voltage in a normal case where smear is not present.

摘要： The present invention provides a thin film magnetic head realizing the gradient and the strength of a perpendicular magnetic field increased as much as possible. A main magnetic pole layer is made recede from a write shield layer. As compared with the case where the magnetic pole layer is not receded from the write shield layer, an overlap range in which the main magnetic pole layer and the write shield layer are overlapped one another is smaller. Accordingly, the amount of magnetic flux emitted from the main magnetic pole layer toward a recording medium relatively increases, and the amount of magnetic flux leaked from the main magnetic pole layer to the write shield layer relatively decreases.

摘要： Disclosed is a process of treating the surface of copper foil without using harmful elements such as arsenic, selenium and tellurium unlike in the prior art. It is possible to, in an easy way, obtain a uniform rough condition and low roughness and produce a high peel strength to such resin base materials as polyimide resin which is weak in peel strength. The process comprises a roughening treatment involving a cathodic electrolysis of at least one side of copper foil near or above the limiting current density in an electrolytic bath containing titanium ions and tungsten ions and prepared by adding sulfuric acid and copper sulfate so as to have copper protrusions deposited and then coating the depositions with copper or copper alloy in a cathodic electrolysis, followed by giving to the surface of the above-mentioned copper or the copper alloy at least one rust-proofing treatment.
