Description

Изобретение относитс  к области приборостроени , в частности к устройствам дл  магнитной записи, где использован магнитный носитель с жесткой основой.The invention relates to the field of instrumentation, in particular to magnetic recording devices, where a magnetic carrier with a rigid base is used.

Известны устройства дл  магнитной записи, в которых использована жестка  основа, например магнитные барабаны и магнитные диски или карты, используемые совместно с магнитными головками.Magnetic recording devices are known that use a rigid base, such as magnetic drums and magnetic disks or cards, used in conjunction with magnetic heads.

Однако при использовании известных устройств зазор между магнитной головкой и носителем достаточно мал, что снижает достоверность записываемой и воспроизводимой информации . Кроме того, износоустойчивость покрытий носителей также недостаточна высока. However, when using known devices, the gap between the magnetic head and the carrier is sufficiently small, which reduces the reliability of the recorded and reproducible information. In addition, the wear resistance of carrier coatings is also insufficiently high.

Целью изобретени   вл етс  уменьшение зазора между магнитной головкой и носителем и повышение износоустойчивости последнего.The aim of the invention is to reduce the gap between the magnetic head and the carrier and increase the wear resistance of the latter.

Эта цель достигаетс  за счет того, что в предложенном устройстве покрытие носител  выполнено в зоне между дорожками в виде кольцевых пазов, заполненных материалом, износоустойчивость которого выше износоустойчивости материала рабочего сло  носител .This goal is achieved due to the fact that in the proposed device, the carrier coating is made in the area between the tracks in the form of annular grooves filled with a material whose wear resistance is higher than the wear resistance of the material of the working carrier layer.

На чертеже показана схема устройства дл  магнитной записи.The drawing shows a diagram of a device for magnetic recording.

На жесткую основу 1 нанос т рабочий слой 2, используемый совместно с участками 3 из износоустойчивого материала. Запись и воспроизведение информации осуществл ютс  магнитными головками, состо щими из корпуса 4 и сердечников 5.A working layer 2 is applied on a rigid base 1, used in conjunction with sections 3 of a wear-resistant material. Information is recorded and reproduced by magnetic heads consisting of body 4 and cores 5.

При этом участки 3, расположенные в междорожечных канавках носител , состо ш,его из основы 1 и рабочего сло  2,  вл ютс  как бы опорой дл  головок и представл ют собой зашитное покрытие рабочего сло  носител .At the same time, the sections 3 located in the interlocking grooves of the carrier, consisting of the base 1 and the working layer 2, are like a support for the heads and constitute the protective coating of the working layer of the carrier.

Предмет изобретени Subject invention

Устройство дл  магнитной записи, содержашее магнитный носитель с жесткой основой, рабочим слоем и покрытием, а также магнитные головки с сердечниками, отличающеес  тем, что, с целью уменьшени  зазора между магнитной головкой и носителем и повышени  износоустойчивости последнего, покрытие выполнено в зоне между дорожками, формируемыми головками, в виде кольцевых пазов , заполненных материалом, износоустойчивость которого выше износоустойчивости материала рабочего сло  носител .A magnetic recording device containing a magnetic carrier with a rigid base, a working layer and a coating, as well as magnetic heads with cores, characterized in that, in order to reduce the gap between the magnetic head and the carrier and increase the wear resistance of the latter, the coating is made in the zone between the tracks, formed by the heads, in the form of annular grooves filled with material, the wear resistance of which is higher than the wear resistance of the material of the working layer of the carrier.
