Abstract
The invention relates to a method for the electrodeposition of a homogeneously thick metal layer on the surface of a substantially flat cathode in which a screening member is placed in the electrolyte bath between the planes of the anode and the cathode. In order to improve the homogeneity of the thickness of the metal layer, which is desired, for example, in the manufacture of information carriers, a cylindrical screening member is used which is placed at a short distance from the cathode.
