Abstract

The case of magnetic record media is produced by mixing high permeability magnetic material including iron, silicon steel, alpum, hypermal, sendust and super sendust with plastic around the magnetic face of magnetic record media. The produced case of magnetic record media has the magnetic shielding capability to protect the recorded information in the inner magnetic face from the outer magnetic world.
