A high magnetic head for floppy disk drives that can prevent crosstalk between magnetic cores. Two nonmagnetic material pieces are joined with two magnetic material pieces, respectively, and track grooves and a winding groove are formed on a surface of each of the two magnetic material pieces. The nonmagnetic material pieces are joined together to form a core block with those surfaces facing each other on which the grooves are formed. The core block is cut to a plurality of front core assemblies. The core assembly includes a magnetic circuit having a magnetic gap, and nonmagnetic spacer members which do not form a magnetic circuit, thereby preventing crosstalk between the magnetic cores constituting the composite type magnetic head.
