Title: Thin film magnetic head
Inventor: FUJITA HIROYUKI
IPC: G11B5/31
Filed: 1992-02-24
Abstract: PURPOSE:To provide a thin film magnetic with high chemical durability by using a fluorine containing polymer as an inter-layer insulating layer of the thin film magnetic head. CONSTITUTION:An insulating layer 2 by a thin film forming technology, a lower part magnetic layer 3, a gap layer 4, an induction coil 5, and an upper part magnetic layer 6 are formed on a alumina.titanium carbide ceramic substrate 1 and a first and a second inter-layer insulating layer 8, 9 are formed in a formed product of a protective layer 7. These insulating layer 8, 9 are formed in about 1.5-8mum thickness e.g. by applying a polymer with a noncrystal fluorine containing aliphatic cyclic structure in a specific film thickness by a spin coating method and subsequently by heat-backing. The fluorine containing polymer is superior in chemical durability, so the durability in use of a magnetic head is high and also it has high durability against chemicals such as a plating solution or a washing solution in the manufacturing process. Thus the inter-layer insulating films 8, 9 with low internal stress are obtained and degradation of the magnetic characteristics is prevented.
