Abstract
A composite type magnetic head core slider including a slider body and a core chip, wherein a slot is formed in the slider body such that the slot is open in an end face of the slider body and located within a width of a central recessed portion between two parallel air-bearing portions formed on a surface of the slider body which is to face a magnetic disk, or within a width of an outer recessed portion disposed on one side of one of the air-bearing portions, which one side is remote from the central recessed portion. The core chip is fixed in the slot such that an upper end portion of the core chip protrudes above a surface of the central or outer recessed portion, and the protruding upper end portion of the core chip is subjected to an operation to form a track portion having a magnetic gap.
