PROBLEM TO BE SOLVED: To provide a method for forming the crown of a levitation magnetic head with mass productivity for simultaneously forming a crown and a cross- crown, for reducing the fluctuation of the shape of the crown and the cross- crown, and for easily changing the shape of the crown and the cross-crown. SOLUTION: An almost rectangular bar 21 is constituted so that one or more magnetic head elements 29... can be lined up in a row on a side wall face 23, and a plurality of grooves 26... are formed between each magnetic head element 29... along the rectangular direction of the bar 21 on the upper face (face to be worked) 24 of the bar 21 so that the upper face (face to be worked) 24 can be turned into a plurality of split faces 24a.... This bar 21 is deformed like an arc along the longitudinal direction, and adhered to a jig 3 having a projecting curved surface 6, and each divided face 24a... of the bar 21 is butted to the working face formed like a recessed curved surface of a lap fixed disc, and the bar 21 and the working face are relatively moved so that each split face 24a... can be lapped. Thus, the crown of a levitation magnetic head can be formed.
