ABSTRACT:
A magnetic shielding device, adapted to protect a magnetic recording member against external magnetic fields, includes a plurality of spaced apart sheets of ferromagnetic material and the total thickness of the spacings between adjacent sheets of ferromagnetic material is selected to be larger than 0.5 mm. In a modification, the spaced sheets are covered with covers and the peripheral portions thereof are welded together. In another modification a sheet of insulating material having a surface area larger than those of the sheets of ferromagnetic material is interposed therebetween.
