Abstract

PURPOSE:To remove the work strain of a core and to improve the work precision of a tape contacting surface, by leaving the circumference of the core gap of the tape contacting surface as a projecting part by grinding work. CONSTITUTION:The tape contacting surface 5 of a head 2 is ground by a grinding stone 10 having recessed parts 11. Through this grinding work, the tape contacting surface 5 is formed into a nearly final profile, but only the circumferences of core gap parts are left as projecting parts 9 which correspond to the recessed parts 11 in the grinding surface. Those projecting parts 9 have, for example, about 10mum height and about 350mum width. Then, lapping work which uses fixed abrasive grains and free abrasive grains is carried out to remove the projecting parts 9, thus finishing the surace into a smooth tape contacting surface. The lapped areas are limited nearly to the projecting parts 9, so the work time is shortened and the work precision of the entire tape contacting surface 5 is improved.
