Изобретение относитс к магнитной записи, а именно к способам изготовлени носителей термомагнитной записи.The invention relates to magnetic recording, in particular, to methods for producing thermomagnetic recording media.
Известен способ изготовлени носител термомагнитной записи путем нанесени магнитной пленки на немагнитную основу. Известный способ позвол ет обеспечить относительную простоту процесса изготовлени носител термомагнитной записи П j,A known method of manufacturing a thermomagnetic recording medium by applying a magnetic film on a non-magnetic substrate. The known method allows to ensure the relative simplicity of the process of manufacturing the carrier of the thermomagnetic recording P j,
Недостаток известного способа состоит в том, что изготовленный в соответствии с ним носитель термомагнитной записи не обладает высокой чувствительностью.A disadvantage of the known method is that the thermomagnetic recording medium made in accordance with it does not have high sensitivity.
Известен также способ изготовлени носител термомагнитной записи путем нанесени магнитной пленки на предварительно подогретую монокристаллическую основу конденсацией паров сплава железа и платины в вакууме 1 ( о мм рт. ст., последующе го отжига и охлаждени до комнатнойThere is also known a method of manufacturing a thermomagnetic recording medium by depositing a magnetic film on a pre-heated single-crystal base by condensation of vapors of an iron and platinum alloy in vacuum 1 (about mm Hg, subsequent annealing and cooling to room temperature).
температуры. Такой способ позвол ет изготовить носитель термомагнитной записи, обладающий относительно высокой чувствительностью 2J.temperature Such a method allows the manufacture of a thermomagnetic recording medium with a relatively high sensitivity of 2J.
Недостаток описанного способа состоит в том, что изготовленный в соответствии с ним носитель термомагнитной записи не обладает высо- i кой разрешающей способностью.The disadvantage of the described method is that the thermomagnetic recording medium made in accordance with it does not have a high resolution.
Цель изобретени - повышение разрешающей способности носител термомагнитной записи.The purpose of the invention is to increase the resolution of a thermomagnetic recording medium.
Указанна цель достигаетс тем, что предварительное подогревание монокристаллической основы ведут до достижени температуры 130-V50 С, отжиг производ т в течение мин при k O-SOO C, а конденсацию паров сплава железа и платины осуществл ют при следующем соотношении компонентов ,, вес. : железо 53-61, платина .This goal is achieved by preheating the monocrystalline base until the temperature reaches 130-V50 ° C, annealing is performed for min at kO-SOO C, and the vapor of the alloy of iron and platinum is condensed in the following ratio of components, wt. : iron 53-61, platinum.
