A magnetic recording medium is fabricated by the electrodeposition of acicular magnetic particles onto an electrically conductive substrate from a mixture that is continuously dispersed and circulated through the electrodeposition vessel. Electrodeposition is effected at a critical electric field strength so that the particles are aligned in solution, and deposited perpendicular to the substrate surface such that the medium is highly densified. By use of anisotropic particles the resultant medium is adaptable for perpendicular recording, and by use of isotropic particles the resultant medium will support both longitudinal and perpendicular recording.
