Complex type thin film magnetic head and production method thereof

摘要

The present invention intends to solve the above described problems and provides a high reliability complex type thin film magnetic head in which high recording magnetic field density is achieved without deteriorating an MR element by heat, and in the case when the complex type thin film magnetic head is of sliding type, eccentric friction likely to occur in a lower magnetic core and a upper magnetic core is relaxed and production method thereof. The complex type thin film magnetic head is structured by forming an MR head portion (Q) on an inductive head portion (P) produced on a base substrate. Conductive coils (4) are formed on the recess portions (2a) formed on the lower magnetic core (2) because the groove portions exist through a first flattening layer (23).
