Abstract

PURPOSE:To improve coercive force as well as to obtain a magnetic film positively and at a high speed by stretching a base material in its lengthwise direction, then evaporating a ferromagnetic material over the base material in a vacuum state, again stretching the base material and evaporating the ferromagnetic material.
