Изобретение относитс к области магнитной записи, а именно к записывающим магнитным головкам.This invention relates to the field of magnetic recording, in particular to recording magnetic heads.

Известна записывающа магнитна головка , содержаща магнитом гкие сердечНИКИ , укрепленные с противоположных сторон немагнитных прокладок 1 . Така записывающа магнитна головка обеспечивает формирование магнитного пол записи ее рабочим зазором, образованным немагнитной прокладкой, расположенной со стороны носител магнитной записи.A known recording magnetic head containing magnetically soft cores, reinforced from opposite sides of the non-magnetic spacers 1. Such a recording magnetic head provides for the formation of a magnetic recording field by its working gap formed by a non-magnetic gasket located on the side of the magnetic recording carrier.

Известна также записывающа магнитна головка, содержаща обмотки, размещенные на идентичных магнитом гких С-образных сердечниках, выполненных с торцами разной ширины и укрепленных в пазах немагнитных обойм с противоположных сторон немагнитных прокладок 2 . В этой записывающей магнитной головке широкий и узкий торцы одного магнитом гкого С-образного сердечника расположены соответственно против широкого и узкого торцов другого магнитом гкого С-образного сердечника . Кроме того, в ней толщина немагнитной прокладки, расположенной между широкими торцами больше толшдны немагнитной прокладки, расположенной между узкими тоцами магнитом гких С-образнык сердечников . Это в значительной степени усложн ет процесс изготовлени записывающей магнитной головки.Also known is a recording magnetic head containing windings placed on identical magnetic soft C-shaped cores made with ends of different widths and fixed in grooves of non-magnetic clips from opposite sides of non-magnetic shims 2. In this recording magnetic head, the wide and narrow ends of one magnet of a flexible C-shaped core are respectively located against the wide and narrow ends of another magnet of a soft C-shaped core. In addition, there is a thickness of a non-magnetic gasket located between the wide ends of a thicker non-magnetic gasket located between the narrow ends of the magnet of soft C-shaped cores. This greatly complicates the process of making a recording magnetic head.

С целью упрощени процесса изготовлени в предлагаемой записывающей магнитной головке широкий торец каждого магнитом гкого С образного сердечника расположен против узкого торца другого магнитом гкого С-образного сердечника.In order to simplify the manufacturing process in the proposed recording magnetic head, the wide end of each magnet of a C-shaped soft core is located opposite the narrow end of another magnet of a C-shaped soft core.

На чертеже изображена предлагаема записывающа магнитна головка, вариант.The drawing shows the proposed recording magnetic head, option.

Claims

The recording magnetic head contains windings 1 placed on identical, magnetically soft C-shaped cores 2, made with ends of different widths. The magnet C-shaped cores 2 are reinforced in grooves 3 non-magnetic holders 4 on opposite sides of non-magnetic gaskets 5. Non-magnetic gaskets 5 are placed between the ends of the magnet 1ШШ C-shaped cores 2. At the same time, the wide end of each magnet of the flexible G-o different core 2 is opposite the narrow end of another magnet with a soft C-shaped core 2. In the recording magnetic head shown in the drawing in a non-magnetic holder 4 there are two pairs of magnetically soft C-shaped cores 2 separated by screen 6. In the proposed The recording magnetic head is a non-magnetic gasket 5, located on the side of the working surface, forms a working gap, and a non-magnetic gasket 5, located on the opposite side, is an additional gap. In the manufacture of the proposed recording magnetic head, between the ends of the magnet of the soft C-shaped cores 2, non-magnetic pads 5 of one thickness or a common non-magnetic film are installed, which can be separated thereafter. However, despite this additional gap has a magnetic resistance of sufficient size. The use of the invention allows to significantly simplify the process of manufacturing a recording magnetic head, which can be used in the equipment for magnetic recording of electrical signals. Claims of the Invention Magnetic recording head comprising windings placed on identical magnetically flexible C-shaped cores, extra-wide with ends of different width and fixed in non-magnetic holders on opposite sides of non-magnetic gaskets, which, in order to simplify the process of manufacturing a magnetic recording head, the end of each magnet of the light C-shaped core is located opposite the narrow end of the other with the magnet of the light C-shaped core.
