Description

: ,,, -, Dechnik 3 at the output of the n-ositel, winding 4 of the excitation, non-magnetic strips 5, magnetic soft strip 6, longitudinal grooves 7 and protrusions 8 in the pole tip of the side core at the exit of the nose 5 bodies. Magnetic flux 9 CTHpafiffS is shown by a dotted line and arrows, ---: ".". ..-., ..- ... ... The size of the carrier bend. using the proposed erase head is as follows. . ; At the beginning of the first stage, the working gap passes through the working gap, which itself represents two working gaps, formed by the Hbix given by a given combination of two non-magnetic and one magnetic g, which is 15. Having undergone double demagnetization in a working blueprint for: zbre7 iosy ....-, - DMY-Nevertheless, it comes at (ebroy: permanent magnetization, caused by, for example, asymmetry, forms of high-frequency 20% erasing track. However the second working gap, the carrier again. Peremagititits in the opposite nap: pa; v1 against the turns 8, and the erase / erasure horn will be broken up into several 25 sub-tracks magnetized in antiphase. Thus, the conditions for compensating the noise of the magnetized carrier are created during the reproduction One of the methods for manufacturing a lateral heart, 5 with given dimensions of tsazov 7 and protrusions 8, may be, in particular, a set of a straight tip or a core of a series of 1-35 magnetized non-magnetic plates of corresponding plates) thickness. : The main advantage of the head, and the combination of double carrier de-magnetisation together with multi-track antiphase erasing, allows us to ((: not only high-quality demagnetized 1, but also keep it if the carrier is randomly magnetized by a constant field during the erase process). - -. .u ... V -t Formula of the invention, Multi-track magnetic head for erasing recordings from Magnetic media, containing magnetic core consisting of central and two side serifiers, and also winding, about Y l and Yusch and with, .Tem ,, in order to reduce noise6 of the receiver: and to improve the quality of erasing, it is equipped with a three-layer composite gasket installed between the planes of the first connector along the movement of the carrier and the central core. The first and third layers of the gasket are filled from a non-magnetic and the second one is made of magnetic soft materials, the pole and the tip of the third side core is made with uniformly spaced one from the other by longitudinal slots with protrusions perpendicular to the working gap ..
