Abstract

PURPOSE:To rationalize a head producing process by forming numbers of heads in one body, and then cutting it into individual heads. CONSTITUTION:Recording element groups 15 and reproducing element groups 16 are formed on the same substrate. At this time, recording elements favorably have greater magnetic film thickness and gap length that reproducing elements, but the recording elements may only be formed by being masked partially with photoresist, etc., at the point of time when the reproducing elements had necessary thickness during the manufacturing process. Next, the substrate 8 is cut along a boundary lines X-X between the recording and reproducing elements and element formed surfaces are joined together through a center shield to obtain a compound thin-film magnetic head.
