Description

где, например, R - алкил с числом атомов углерода в молекуле, равным 10;where, for example, R is alkyl with the number of carbon atoms in the molecule equal to 10;

л - целое число, равное 2;L is an integer equal to 2;

т - целое число, равное 3.t is an integer equal to 3.

При этом смесь оксипронилированных эфиров пентаэритрита и алкнлфосфоновой кнслоты вз та, например, в количестве 2,2% от общего веса магнитных частиц.In this case, a mixture of oxypronylated pentaerythritol esters and alknolphosphonic acid is taken, for example, in an amount of 2.2% of the total weight of magnetic particles.

Использование изобретени  нозвол ет в значительной етеиени уменьшить шероховатость рабочего сло  носител  магнитной заииси. Кроме того, исиользозание изобретени  обеспечивает эластичность рабочего сло  носител  магнитной записи и равномерность распределени  магиитных частиц в св зуюндем веществе .The use of the invention makes it possible to significantly reduce the roughness of the working layer of the magnetic seal carrier. In addition, the use of the invention ensures the elasticity of the working layer of the magnetic recording carrier and the uniform distribution of magical particles in the bonded substance.

Предлагаемый рабочий слой может найти применение в носителе магиитной записи, нредиазначенном дл  заииси как аналоговой, так и цифровой ииформации.The proposed working layer can be used in a magic recording medium, designated for recording both analog and digital information.
