Abstract
PURPOSE: To obtain a high-stability and high-reliability head by providing the first thin layer having a magnetoresistance effect on a substrate and providing the second thin layer, which can be etched selectively, on the first thin layer and providing a photo resistor layer on the second thin layer and performing a post-processing.
CONSTITUTION: Layer 2a having a magnetoresistance effect (MR effect) such as Permalloy is formed on substrate 1 such as silicon by evaporation, etc., and next, Al thin layer 5 is formed, and next, photo resistor layer 6 is provided. Next, mask alignment, exposure to light and development are performed, and exposed Al layer 5 and Permalloy layer 2a are removed by etching. Next, resistor layer 6 is removed to obtain a MR element. Thus, since no resistor is caused to adhere onto the MR element, a head of a low resistance value of 7W9Ω and of a uniform and stable characteristic can be obtained by utilizing a photo resistor to connect Cr, Au, etc., of signal leading-out conductors and the MR element after evaporation or sputtering of Cr, Au, etc. Then, the contact part is not burned even if a large current is flowed to the MR element, so that the output can be large.
