Abstract: A laminated magnetogram carrier, esp. UTR tape, with a layer, based on finely-divided magnetic pigment dispersed in a binder and suitable for magnetic recording, on a non-magnetisable support, contains 0.2-4, pref. 0.4-2 wt%, w.r.t. the wt. of the magnetic pigment, of a mixt. of aliphatic 14-18C monocarboxylic acids with m.pt. 50-60, pref. 52-55 degrees C. The acids are pref. added to the dispersion before application to the support.

Abstract: A machine for coating magnetic tape uses a method of replacing a running out foil band by a new foil band, where, shortly before running out, and without interrupting a continuous run, a new roller is moved in the winding machine and accelerated to replace the nearly used roller. Subsequently the bands of both rollers are joined together without altering their speed. Ultimately the end piece of the band of the nearly empty roller is cut off and the tension of the new band adjusted and the empty roller stopped. The new band roller (9) is, during its rotation through less than 360 deg. from stand still, accelerated to 90% - 98% of the speed of the running out foil band (2) and when both the bands (2, 9) are joined together, the acceleration is stopped and the tension of the new band is adjusted without subjecting it to shocks.

Abstract: The invention relates to magnetic recording media comprising a non-magnetic base and, applied thereto, a firmly adhering magnetic coating based on a finely divided magnetic pigment and a special binder mixture. This binder mixture consists essentially of 20 to 90 percent by weight of an elastomeric polyurethane which is soluble in a volatile organic solvent, is practically free of isocyanate groups and has been obtained from a linear, aliphatic polyester or polyether and a diisocyanate of 6 to 24 carbon atoms, and of 10 to 80 percent by weight of a vinyl chloride copolymer which contains 50 to 90 percent by weight of vinyl chloride units and 10 to 50 percent by weight of units of one or more diesters of maleic acid with an alcohol of 1 to 3 carbon atoms, or of the reaction product of this binder mixture with a polyisocyanate of 6 to 50 carbon atoms. Magnetic coatings containing such a binder mixture are distinguished by improved surface hardness coupled with improved orientability of the magnetic particles, as a result of which such recording media are particularly suitable for modern video- and audio-recording instruments.
