Abstract
PURPOSE: To increase the output and the reliability, by forming an adhering layer through the removal of silicon film on heat-resistant resin film on the coil upper surface, in a thin film magnetic head, and by forming low melting point glass layer on the adhering layer via a reaction preventing layer.
CONSTITUTION: On a substrate 1, a lower magnetic-substance layer 2, the 1st gap SiO2 film 3, coil 4 heat resistance resin film 5, the 2nd gap SiO2 film 6, upper magnetic-substance layer 7, and protection SiO2 are sequentially laminated to form a thin magnetic head. Next, after removing silicon films 6, 8 on the heat resistant resin film 5 on the upper surface of the coil 4, and an upper magnetic substance layer 7 with etching, an adhering layer 11 consisting of aluminum is formed on the entire surface, the reflection preventing layer 12 consisting of chromium is formed on it, and the upper part of it is entirely coated with a low melting point glass 13. As a result, the damage at the baking of a low melting point glass 13 can be prevented.
