发明名称 Thin film magnetic head having a plurality of coil layers
摘要 A thin film magnetic head having a plurality of coils is capable of recording with higher density. A magnetic pole section for restricting a track width is formed between a lower core layer and an upper core layer, and two coil layers are tiered between a reference surface and a lower core layer through the intermediary of a coil insulating layer. This allows a magnetic path to be shortened. As a result, narrower tracks and lower inductance can be both achieved, and the narrower tracks combined with faster data transfer enable higher-density recording to be attained.
