Description
Изобретение относится к магнитной записи, а именно к способам изготовления носителей термомагнитной записи.The invention relates to magnetic recording, and in particular to methods of manufacturing a carrier of thermomagnetic recording.
Известен способ изготовления носителя термомагнитной записи путем нанесения магнитного слоя на немагнитную основу. Известный способ позволяет обеспечить относительную простоту процесса изготовления носителя термомагнитной заИиси р J.A known method of manufacturing a carrier of thermomagnetic recording by applying a magnetic layer to a non-magnetic base. The known method allows to ensure the relative simplicity of the manufacturing process of the carrier of thermomagnetic zaisi p J.
Недостаток известного способа состоит в низких магнитных свойствах изготовленного в соответствии с ним носителя термомагнитной записи. ( A disadvantage of the known method is the low magnetic properties of a thermomagnetic recording medium manufactured in accordance with it. (
Известен также способ изготовления носителя термомагнитной записи путем нанесения магнитной пленки на предварительно подогретую поликристаллическую основу конденсацией .There is also known a method of manufacturing a carrier of thermomagnetic recording by applying a magnetic film to a preheated polycrystalline base by condensation.
в вакууме паров сплава кобальта и пластины. Такой способ позволяет обеспечить получение относительно высоких магнитных свойств изготовлен2 ,ηογο в соответствии с ним носителя 'термомагнитной записи [2].in a vacuum vapor cobalt alloy and plate. Such a method makes it possible to obtain relatively high magnetic properties manufactured2, ηογο in accordance with it, the carrier of the thermomagnetic record [2].
Недостаток способа состоит в значительной длительности процесса изготовления носителя термомагнитной записи.The disadvantage of this method is the significant duration of the manufacturing process of the carrier of thermomagnetic recording.
Цель изобретения - уменьшение длительности процесса изготовления носителя термомагнитной записи.The purpose of the invention is to reduce the duration of the manufacturing process of the carrier of thermomagnetic recording.
Указанная цель достигается тем, что после конденсации в вакууме сплава кобальта и платины производят гамма-облучение магнитной пленки.This goal is achieved by the fact that after condensation in vacuum of an alloy of cobalt and platinum produce gamma radiation of a magnetic film.
Способ осуществляется следующим образом.The method is as follows.
На предварительно подогретую поликристаллическую основу наносят магнитную пленку конденсацией в вакууме паров сплава кобальта и платины, причем предварительное подогревание поликристаллической основу производят до температуры 100°С, а конденсацию паров сплава кобальта и платины осуществляют а вакууме 10~4мм рт.ст. После конденсации в вакууме паров сплава кобальта и платины производят гамма-облучение магнитной пленки.A magnetic film is applied to a preheated polycrystalline base by condensation of the cobalt and platinum alloy vapors in vacuo, and the polycrystalline base is preheated to a temperature of 100 ° C, and cobalt and platinum alloy vapors are condensed in a vacuum of 10 ~ 4 mm Hg. After condensation in vacuum of the vapor of an alloy of cobalt and platinum produce gamma radiation of a magnetic film.
Использование изобретения позволя- j ет в значительной степени уменьшить длительность изготовления носителя .термомагнитной записи, а также обеспечивает простоту процесса изготовления носителя термомагнитной записи.The use of the invention makes it possible to significantly reduce the duration of the manufacture of a magnetic recording medium, and also provides the simplicity of the manufacturing process of a thermomagnetic recording medium.
