Title: Production of magnetic recording medium
Inventor: MATSUFUJI AKIHIRO
IPC: G11B5/842
Filed: 1985-11-13
Abstract: PURPOSE:To prevent the injuring and drop-out of a magnetic layer in a cut part by forming a magnetic coating layer contg. ferromagnetic powder on a nonmagnetic layer, cutting the layer to a desired shape then heating the layer to cure the coating layer. CONSTITUTION:The magnetic coating layer formed by dispersing the ferromagnetic powder into a binder component consisting of a resin component and polyisocyanate compd. at 9:1-5:5 ratio by weight is coated on the nonmagnetic layer. The magnetic powder is pulverized ferromagnetic metallic powder having >=42m<2>/g specific surface area. The elimination of the pulverized powder is effectively prevented during running by the use of the polyisocyanate compd. The surface is smoothed after coating and drying to annihilate the pores generated after the solvent removal, by which the contact with a head is improved. Three-dimensional network crosslinked structure is then formed by heating for >=24hr at >=40 deg.C after cutting. The injuring and drop-out in the cut part of the magnetic layer are thus eliminated by cutting prior to curing by heating.
