Изобретение относитс к приборостроению и может быть использовано в технике магнитной записи, например, в кодовых магнитных накопител х.The invention relates to instrument engineering and can be used in magnetic recording techniques, for example, in code magnetic drives.

Известен способ изготовлени носител , магнитной записи с несколькими магнитными сло ми, отличающимис относительным уровнем копирэффекта DlПри записи на этот носитель требуютс различные токи записи и плотность записи недостаточно высока.There is a known method of manufacturing a carrier, magnetic recording with several magnetic layers that differ in the relative copy-effect level. Dl When recording on this carrier, different recording currents are required and the recording density is not high enough.

Наиболее близким к предлагаемому вл етс способ изготовлени носител магнитной записи, при котором на основу нанос т магнитные слои с различными магнитными характеристиками Г21.Closest to the present invention is a method of manufacturing a magnetic recording medium in which magnetic layers with different magnetic characteristics G21 are applied to the substrate.

К недостаткам этого способа от- нос тс сравнительно высокие энергозатраты при записи информации на магнитнь й носитель и недостаточно высока плотность записи.The disadvantages of this method are relatively high energy consumption when recording information on magnetic media and the recording density is not high enough.

Цель изобретени - снижение энергозатрат при записи информации на магнитный носитель и повышение плотности записи.The purpose of the invention is to reduce energy consumption when recording information on a magnetic medium and to increase the recording density.

Поставленна цель достигаетс за счет того, что в способе изготовлени носител магнитной записи, при котором на основу носител нанос т магнитные слои с различными магнитными характеристиками, магнитна This goal is achieved due to the fact that in the method of manufacturing a magnetic recording carrier, in which magnetic layers with different magnetic characteristics are applied to the carrier substrate, magnetic

Claims

The magnetic layers have different magnetic susceptibility with relatively stable for layers coercive force values with fluctuations of no more than 10% of the chosen nominal value, and the susceptibility should increase in layers no more than 10-15% of the selected value of the previous layer . The use of the invention makes it possible to use the recording current to accumulate the carrier across the entire thickness, to increase the recording density by a factor of 3–4, to increase the reliability of the reproduction of the recording, and to significantly reduce the energy consumption for recording information. Claims The method of manufacturing a magnetic recording medium in which magnetic layers with different magnetic characteristics j are applied to the base of the carrier are characterized in that, in order to reduce energy costs when recording information on magnetic media and to increase the recording density, the magnetic susceptibility of each magnetic layer increases by 10-15%, and the magnetic layers themselves are separated from each other by diamagnetic layers.
