Description

Изобретение относится к приборостроению и может быть использовано в аппаратуре магнитной записи.The invention relates to instrumentation and can be used in magnetic recording equipment.

По основному авт. св. № 667990 известна интегральная магнитная головка (ИМГ), содержащая параллельные Ма гнитопроводы и обмотку, каждый виток которой выполнен в виде меандра, причем одно крайнее плечо расположено над верхним магнитопроводом, другое крайнее плечо - под нижним магнитопрово- ¹дом, а среднее - между верхним и нижним магнитопроводами flj.According to the main author. St. No. 667990 known integrated magnetic head (IMG), containing parallel magnetic cores and a winding, each coil of which is made in the form of a meander, with one extreme arm located above the upper magnetic circuit, the other extreme arm - under the lower magnetic circuit ¹ house, and the middle - between the upper and lower magnetic circuits flj.

Недостатком известной конструкции является малый коэффициент полезного действия, так как в магнитопроводе магнитный поток индуцируется неравномерно, значительно спадая от И —ого витка к (П+1)-му витку, в результате чего” потоки рассеяния получаются ослабленными.A disadvantage of the known construction is the small efficiency, since the magnetic flux in the magnetic circuit is induced unevenly, significantly decreasing from the I-th turn to the (P + 1) -th turn, as a result of which the scattering fluxes are weakened.

Цель изобретения - повышение коэффициента полезного действия интегральной магнитной головки.The purpose of the invention is to increase the efficiency of the integrated magnetic head.

Поставленная цель достигается тем,, что в интегральной магнитной головке среднее плечо каждого витка смещено относительно крайних плечей на полшага, причем зазор между витками выполнен меньше ширины витка.The goal is achieved by the fact that in the integrated magnetic head, the middle arm of each turn is offset relative to the extreme arms by half a step, and the gap between the turns is made smaller than the width of the turn.

На фиг. 1 показана конструкция интегральной магнитной головки,* на фиг. 2потенциальная магнитограмма.In FIG. 1 shows the construction of an integrated magnetic head, * in FIG. 2potential magnetogram.

Интегральная магнитная головка содержит расположенные один над другим нижний 1 и верхний 2 магнитопровод, а также многовитковую обмотку 3, выполненную в виде меандра. Средние плечи меандра 4 смещены относительно крайних плеч 5 на полшага, при этом ширина витков больше промежутка между витками.The integral magnetic head contains one lower 1 and upper 2 magnetic core located one above the other, as well as a multi-turn winding 3 made in the form of a meander. The middle shoulders of the meander 4 are offset relative to the extreme shoulders 5 by half a step, while the width of the turns is greater than the gap between the turns.

Индуцированная намагниченность магнитопровода от крайних плеч 5 изображена на фиг. 2а, а от средних плеч 4 на фиг. 26.The potential magnetogram depicted in FIG. 2, explains the operation of the integrated magnetic head. The induced magnetization of the magnetic circuit from the extreme arms 5 is shown in FIG. 2a, and from the middle arms 4 in FIG. 26.

Суммарная магнитограмма намагниченности Магиитопровода на фиг. 2в показывает, что неравнолучность намагниченности магнитопровода снижена в 4-5 раз. Аналогичное утверждение распространяется и на нижний магнитопровод 1 в силу симметричности картины.The total magnetogram of the magnetization conduit in FIG. 2c shows that the non-equilibrium magnetization of the magnetic circuit is reduced by 4-5 times. A similar statement applies to the lower magnetic circuit 1 due to the symmetry of the picture.

Изобретение позволяет увеличить КПД головки не менее, чем в 2 раза и уменьшить паразитную модуляцию намагниченности носителя записи (на чертеже не показан) и, следовательно, повысить надежность аппаратуры памяти.The invention allows to increase the efficiency of the head by at least 2 times and reduce spurious modulation of the magnetization of the recording medium (not shown in the drawing) and, therefore, increase the reliability of the memory equipment.

Claims

The invention relates to instrumentation and can be used in magnetic recording equipment. According to the main author. St. No. 667 99O known integral magnetic head (IMG), containing parallel to and connector lines and a winding, each turn of KOfopoA is made in the form of a meidor, one extreme shoulder located above the upper magnetic conductor, the other extreme shoulder below the lower magnetic conductor, and the middle shoulder between the upper and lower magnet gadfly jlj. A disadvantage of the known construction is a low efficiency, since the magnetic flux in the magnetic core is induced unevenly, due to the drop from the nth loop to the (n + 1) th loop, as a result of which the scattering flows are weakened. The purpose of the invention is to increase the efficiency of the integral magnetic head. The goal is achieved by that in the integrated magnetic head the middle shoulder of each turn is offset relative to the extreme shoulders by half a step, and the gap between the turns is made smaller than the width of the turn.
