ABSTRACT:
Employed is a crown forming method of forming a crown on a floating type magnetic head which includes the steps of placing an approximately rectangular-prism-shaped bar, which has magnetic head elements of not less than 1 formed on a side wall thereof in a row, on the convex surface of a jig whose radius of curvature is R.sub.1 through an elastic sheet while facing the upper surface (surface to be processed) of the bar to a lapping surface plate having a concave processing surface whose radius of curvature is R.sub.2 with the relationship between the radius of curvatures set to R.sub.1 .gtoreq.R.sub.2, deforming the bar to an arc shape along the longitudinal direction thereof and bonding it on the convex surface together with the elastic sheet, and lapping the upper surface (surface to be processed) by abutting it against the processing surface and moving the upper surface (surface to be processed) relative to a processing surface.
