磁気ヘツド。 In a composite floating magnetic head consisting of a non-magnetic slider and a head core that levitates above a magnetic recording medium and performs recording/reproduction on the magnetic recording medium, the head core has a high saturation magnetic flux density on at least one side of the gap forming surface of the gap portion. The metal-in-gap structure is coated with a metal magnetic thin film, and the angle θ formed by the sliding surface in contact with the magnetic recording medium and the gap forming surface on the air outflow end side with the gap part sandwiched therebetween is 9.
A composite floating magnetic head characterized by being set at 0 degrees or less.
