A process for producing a magneto-optic recording medium, in which a primary layer, which adheres closely to a substrate, is formed by means of sputtering in a gas-discharge atmosphere, comprises a step in which the pressure of the discharge gas is set such that the relationship lambda s >/= 1TS is satisfied, lambda s denoting the average free path length of the sputtering atoms and 1TS denoting the distance between a sputtering target and the substrate, thus forming the primary layer, which exhibits strong adhesion with respect to the substrate.
