A process for the preparation of a magnet arrangement tra eger recording with a magnetic layer of with a substantially from lecithin existing mono molecular layer by means of crossed magnet powder part chen

摘要

PURPOSE:To improve residual magnetic flux density, rectangular ratio and packing density by improvement of dispersibility of magnetic powders using a high purity product of lecithin for pre-treatment of magnetic powders, resulting in excellent surface characteristics and abrasion resistance of magnetic tape.
