Abstract
A floating magnetic head including a spacer, made from a nonmagnetic substance and which is equal or longer than a head core, is interposed between a slider made from a magnetic substance and the head core. In an alternative embodiment, a part of the slider is made from a nonmagnetic substance and the head core is secured thereon, and coils are wound in opposite senses around core legs of the head core. The present invention shields a noise of an external magnetic field with the slider and improves a recording performance because the slider is isolated magnetically and a magnetic resistance of the slider becomes smaller than that of the head core.
