Abstract: In the production of magnetic storage disks, metal substrate disks (2) are subjected to a plurality of treatments in baths (18) for cleaning, activating and coating the disk surface. A large number of disks are treated simultaneously using a frame having one or more bars (1) on which a plurality of the substrate disks (2) are arranged through their central orifice and which are detachably fastened at their ends in retaining means (3, 7). For washing the disks after each treatment, the frame is provided with spray means (19, 20) which is arranged above the bars (1) and is detachably connected to a water supply. Conveying and lifting means move the frame to, and introduce the frame into, the treatment baths (18).
