PURPOSE:To grind a magnetic head into a shape for obtaining an optimum abutment with respect to a magnetic disk by correspondingly arranging the magnetic head and a pad member with a flexible lapping disk sandwiched and abutting the pad member on the lapping disk. CONSTITUTION:A jig supports the magnetic head 1, which is permitted to deal with one side of the flexible lapping disk 4 which is fitted to a spindle 3 in a way that is rotates similarly with the magnetic disk and the pad member 7 is arranged on the opposite side of the magnetic disk 1 with the lapping disk 4 sandwiched. The pad member 7 is abutted on the other surface of the lapping disk 4, and one surface is permitted to abut on the tip surface of the magnetic head in a deformed shape. With the spindle 3, the lapping disk 4 is rotated and the tip surface of the magnetic head is ground. Since the tip surface is ground and generated in a curved surface which is mostly similar to a head abutment deformation when the magnetic disk is recorded and reproduced, satisfactory abutment with respect to the magnetic disk can be obtained, and a highly precise processing formation in the form fitted to the deformation of the magnetic disk can be executed so as to obtain optimum abutment, whereby recording and reproduction can securely be executed.
