Abstract: In a container for a plurality of disk-shaped articles, the partly opened base portion possessing receiving grooves consists of two substantially identical parts which can be assembled, and two further, substantially identical cover parts which at least partially close the openings, and means are provided for disengageably locking the parts of the base portion to the cover parts. Interlocking stacking means are used for stacking a plurality of the base parts, with or without cover parts. The container of the parts of the base portion are useful for any transportation and archiving purposes during production of the articles or by their end users.

Abstract: The invention relates to magnetic discs in which first a non-magnetic intermediate layer and then the magnetic coating are applied by conventional methods to an aluminum disc. The intermediate layer applied to the non-magnetic metallic carrier disc is a hard non-magnetic coating which can be polished and which consists of a dispersion of a pulverulent mixture of finely divided inorganic non-magnetic pigments having a Mohs' hardness of at least 7 in a binder which can be cured and which provides firm cohesion of the pigment particles and good adhesion thereof to the non-magnetic base disc, the pigment mixture containing at least 3 percent by weight of corundum powder having a particle size of from about 1 to 20 mu u. Magnetic discs with very thin magnetic coatings which possess good magnetic and mechanical properties and whose thickness varies only minimally are thus produced in a simple manner.
