。[Claims for Utility Model Registration] An FDD in which a magnetic head for reading and writing a high-density recording medium and a magnetic head for reading and writing a low-density recording medium are arranged adjacent to each other with a non-magnetic material in between. At least in a magnetic head for high-density recording media, the core chip of the magnetic head is exposed to sliding near the gap, and is formed in an oblique shape that recedes from the sliding surface as it moves away from the gap on both sides in the sliding direction. The ferromagnetic material is composed of a ferromagnetic material, and a non-magnetic material that fills the space between the diagonal shaped part where the ferromagnetic material recedes and the sliding surface, and the parts on both sides of the diagonal shaped part in the sliding direction. Features of magnetic head for FDD.
