Abstract: PROBLEM TO BE SOLVED: To provide a method of evaluating paint by which the particle dispersibility, etc., in the paint used for forming each layer constituting a coated magnetic recording medium can be evaluated with higher accuracy in the state of coating at the time of evaluating the particle dispersibility, etc.
SOLUTION: In this method, the particle dispersibility in the paint is evaluated by the laser light scattering method after the particles contained in the paint are dispersed by diluting the paint. The particle dispersibility is evaluated by measuring the particle size distribution in the paint by the ultrasonic attenuation spectroscopic method and the surface condition of the coating film formed of the paint is evaluated based on the evaluated dispersibility. The ζ-potential of the paint is measured by the colloid vibration current method and the surface condition of the paint film is evaluated based on the measured ζ-potential.

Abstract: PURPOSE:To obtain the titled medium provided with a protective film having a low friction coefficient and excellent wear resistance and lubricity by forming 1-9 odd built-up films of the monomolecular layers of trialkylphosphine oxide on a ferromagnetic metallic thin film. CONSTITUTION:A ferromagnetic metallic thin film is formed on a nonmagnetic carrier in a magnetic recording medium and 1-9 odd built-up films of the monomolecular layers of trialkyphosphine oxide is formed on the ferromagnetic metallic thin film. The trialkylphosphine oxide is shown by the formula and has a P=0 group showing excellent affinity for the ferromagnetic metallic thin film and an alkyl group exhibiting an excellent lubricating effect. When a soln. obtained by dissolving the compd. in a volatile solvent, for example, with the Langmuir-Blodgett's technique is added dropwise into the underlying liq. such as water 2 and left standing under an appropriate surface, molecules are easily arranged to form a monomolecular layer. Consequently, the monomolecular layers 3 are built-up on the surface of the ferromagnetic metallic thin film 4, the molecules are densely arranged and a lubricating film having uniform thickness is formed as the protective layer.

Abstract: PURPOSE:To improve the rust preventive property, friction characteristic, and abrasion resistance of the titled magnetic recording medium by forming a protective film of a monomolecular layer of a higher fatty acid or its metallic salt or especially of one or two monomolecular layers which are formed under conditions where the surface pressure is regulated to >=35dynes/cm on a magnetic thin film. CONSTITUTION:A protective film of a monomolecular layer of a higher fatty acid or its metallic salt is a uniform film wherein molecules are densely arranged in a single layer, and has an excellent lubricating characteristic. The friction coefficient is regulated to =35dynes/cm surface pressure. The friction coefficient when the number of the built-up films of a monomolecular layer is odd (one layer), namely the alkyl group is directed toward the surface side is smaller than the friction coefficient when the number is even (2 layers). Besides, the still time is controlled to >=6.5hr by the protective film, and the film is superior in abrasion resistance. Meanwhile, when the surface of a magnetic recording medium after shuttling is observed, the surface roughness decreases as the number of the built-up films of a monomolecular layer decreases, and the surface roughness can hardly seen in one or two monomolecular layers.
