Abstract
At least a part of the insulation layers is made of an insulation material which increases electric conductivity thereof when an ultraviolet radiation is irradiated. Thus, improved resistance properties against ESD can be obtained during fabrication.
Claims8
A thin-film magnetic head comprising insulation layers, at least a part of said insulation layers being made of an insulation material which increases electric conductivity thereof when an ultraviolet radiation is irradiated,
- wherein said thin-film magnetic head includes a magnetoresistive effect element having shield gap layers, a magnetoresistive effect film sandwiched by said shield gap layers and lead conductors connected to said magnetoresistive effect film and sandwiched by said shield gap layers, and
- wherein said at least a part of said insulation layers includes said shield gap layers.
