Summary:A floating-type magnetic head comprising a slider (16) and a core chip (25) secured thereto. The core chip (25) comprises a pair of core segments joined together with a gap spacer (3) and a thin ferromagnetic metal film (2) which are formed at the joint only over a portion of the entire area of the joint which portion terminates at the face of the core chip (25) to be opposed to magnetic recording media. The two core segments area bonded to each other with glass (5) present over the remaining portion of the joint area. In producing the magnetic head, the core chip is prepared by fabricating a core block comprising a pair of base plates joined together and strips of thin ferromagnetic metal film and gap spacer provided at the joint, and machining the core block.
