Abstract
A magnetic read/write transducer head of the type utilizing thin film materials. The method of manufacture comprises steps which deposit a thin film magnetic recording head on a selected substrate having dimensions which enable batch manufacture of a thin film magnetic transducer in combination with its supporting slider assembly. The substrate of selected material in large wafer form is subjected to a series of thin film deposition, etching and plating operations to form a plurality of thin film magnetic heads thereon. Thereafter, the substrate wafer is diced around each thin film magnetic transducer head with subsequent finishing and polishing to requisite shape thereby to yield the complete integrated slider and transducer head assembly.
