摘要:
A thin-film magnetic circuit board is disclosed which includes: a substrate formed of a non-magnetic material; a connector formed from a magnetic film on one major surface of the substrate, the connector having opposite end portions which protrude from the substrate to form a pair of protrusions; at least one coil formed from an electrically conductive film to provide a circuit pattern on the one major surface of the substrate, each coil having a spiral shape and surrounding a corresponding one of at least one of the protrusions of the connector; and a pair of leads which are electrically connected to opposite ends of the circuit pattern formed by the coil(s). Also is disclosed a magnetic head including this thin-film magnetic circuit board and a core element having a magnetic gap.
