Изобретение относитс к области приборостроени и может быть применено практически в любом аппарате магнитной записи.The invention relates to the field of instrumentation and can be applied in virtually any magnetic recording apparatus.

Магнитные головки состо т из корпуса полусердечников и обмоток и вл ютс не ре гулируемыми, что не всегда удобно и практично . Использование устройств регулировани параметров магнитны:х головок или сложно по своей конструктивной особенности , или требует необратимых капитальных затрат 2 .Так, дл регулировани параметров магнитной головки используетс устройство, имеющее в своем составе около шестнадцати элементов, требующих весьма точной обработки, или же один из полусердечников выполн етс с большими пропусками , которые в дальнейшем уничтожаютс , чем и достигаетс регулировка параметров головки. Известна также магнитна головка, содержаща корпус, помещенные в нем полусердечники, между концами которых сформированы передний рабочий и задний вспомогательный зазоры, обмотки, расположенные на полусердечниках. И в этом случае регулировка параметров головки еложMagnetic heads consist of a half-body and windings and are not adjustable, which is not always convenient or practical. The use of parameter control devices is magnetic: x heads are either complex in their design features, or require irreversible capital costs. 2 So, to adjust the parameters of the magnetic head, a device is used that has about sixteen elements that require very precise processing or one of the half cores. it is performed with large gaps, which are subsequently destroyed, and this is achieved by adjusting the parameters of the head. Also known is a magnetic head, comprising a case, half-hearts placed in it, between the ends of which the front working and rear auxiliary gaps are formed, windings located on the half-hearts. And in this case, the adjustment parameters of the head

на и не обладает достаточно высокой точностью .on and does not have a sufficiently high accuracy.

Цель изобретени - повышение точности и упрощение процесса регулировки параметров магнитной головки. Дл этого головка снабжена стержнем, имеющим форму параллелепипеда и обладающим меньшим по сравнению с участком заднего зазора магнитным сопротивлением, каждый полусердечник имеет со стороны заднего зазора выступ, при этом выступы совместно с прилегающими к ним сторонами полусердечников образуют П-образный паз, в полости которого и устанавливаетс о возможностью перемещени стержень.The purpose of the invention is to improve the accuracy and simplify the process of adjusting the parameters of the magnetic head. For this, the head is equipped with a rod having the shape of a parallelepiped and having a smaller magnetic resistance compared to the back gap, each half-core has a protrusion from the back gap, and the projections together with the adjacent sides of the half-cores form a U-shaped groove, in which cavity and establishes the ability to move the rod.

На чертеже показана описываема магнина головка.The drawing shows the described magnin head.

Claims

The magnetic head consists of two half-holes 1 and 2, in which half-hearts 3 and 4 are placed. Each of the half-hearts has a protrusion 5 and 6 and a winding 7 and 8. Non-magnetic spacers 9 and 10 are located in the working gaps. The space with spacer 9 is the main working gap located in the front of the head, and the gap with the gasket 10 - an auxiliary gap located in the rear of the head. Therefore, one of the zagzors is the front one and the other is the rear one. A rod 11 is used in the head. parallelepiped-shaped. The protrusions of the half-cores with the sides of the half-cores adjacent to them form a U-shaped groove 12, in which the rod 11 is placed. By moving the core in the cavity of the groove, it is possible to adjust the head parameters within the required limits. The proposed head simplifies and improves tuning accuracy and reduces its cost. Claims of Magnetic Head, comprising a case, half-hearts placed in it, between the ends of which front working and rear auxiliary clearances are formed, and windings located on the half-core, characterized in that, in order to improve the accuracy and simplify the process of adjusting its parameters, the head is provided a rod having the shape of a parallelepiped and smaller relative to the back gap section is magnetic resistance, and each half core has a protrusion from the side of the same gap, with protrusions from the abutment The sides of the half-cores to them form a U-shaped groove, in the cavity of which the rod is mounted so that it can move.
