Abstract

PURPOSE:To ensure contact between a head and a magnetic tape under actual use conditions by performing the front lapping process of the magnetic head, which is used in a rotary head-type magnetic picture recording and reproducing device, under conditions approximating the use state for recording and reproducing. CONSTITUTION:In the process of magnetic head chip 17, head chip 17 is fixed to vertically movable head front processing means (for example, bimorph 15 constituted by a piezo-electric element where a control voltage is applied to move vertically at the process time), and the front lapping process is performed while moving vertically head chip 17, and the tip form (specially, a width-direction sectional form) is so controlled that the contact state between head chip 17 and magnetic tape 20 may be best under all conditions shown in figure B. Then, it is desirable that the movement quantity of the magnetic head at this time is equal to or slightly larger than the auto-tracking control width for incorporation into a VTR and actual use.
