Disk-shaped nickel-plated aluminum substrates which are used as bases in the production of magnetic recording disks having a magnetizable metallic layer are surface treated by polishing and texturing.

Surface treatment of disk-shaped nickel-plated aluminum substrates

A magnetic recording disk comprising a non-magnetic substrate and two or more firmly adhering magnetizable layers applied to one or both sides thereof, the layer located directly on the substrate being magnetically isotropic, while the second layer and any additional layers exhibit orientation of the anisotropic magnetic particles parallel to the substrate and to the envisaged recording direction.

Magnetic recording disk

A process and apparatus for the manufacture of magnetic recording media, in which, immediately before the magnetic dispersion is applied to a base, the dispersion is subjected to shear by means of a disc rotatably mounted in a housing, by introducing it at the center of rotation of the disc and forcing it through a gap formed between the face of the disc and the wall of the housing, which gap tapers toward the rim of the disc.

Process for the manufacture of magnetic recording media

A process for the manufacture of rigid magnetic recording media by depositing a cobalt-containing ferromagnetic metal layer on a non-magnetic metallic base disc provided with a cured layer of binder which does not dissolve or swell in organic solvents and contains non-magnetic pigments, and which has been activated, before deposition of the ferromagnetic layer, by treatment with a solution of a palladium (O) complex in an organic solvent, followed by decomposition of this complex, to prepare it to receive the ferromagnetic metal layer which is produced by electroless deposition.

Process of making a magnetic recording medium

A container for a disc-shaped recording medium and a drive unit for use with the container, the drive unit being provided with means for increasing the distance between the lower and upper walls of the container, which latter comprises flexible elements. This design permits very high scanning speeds. The container/drive unit combination of the invention can be advantageously employed for recording and/or for reproducing data, video and instrumentation signals.
