Abstract
A thin, ferromagnetic layer which can be continuous, substantially pit-free and uniform, said layer having high bit density capabilities consisting essentially of cobalt in the form of close packed hexagonal crystals. A substrate is treated with a catalytic activator upon which is deposited an electroless conductive layer, such as copper; the cobalt layer is deposited by electroplating on the conductive layer. The ferromagnetic layer has a nominal coercivity of about 200 to about 500 oersteds and exhibits no anisotropy in the plane of deposition.
