Abstract

The invention relates to magnetic recording and makes it possible to increase the degree of maintainability. Between the two semi-blocks 1 and 2, each of which contains C-shaped half-cores 3 with windings, a non-magnetic insert 5 is placed with poles 6 fixed with grooves 7 with a working gap 7. To assess the degree of wear, tips 6 can be installed in the insert 5 with a protrusion by an amount comparable to the depth of the working gap 7. The fulfillment of the pole tips of a constricted shape contributes to a higher recording density by localizing the magnetic field in the area of the working gap 7. Pole tip tips can be made in the form of a removable C-shaped core with two working gaps on its opposite sides. 1 3.p.f-ly, 7 ill. with S (L

Description

I

The invention relates to a technique of magnetic recording, in particular, to magnetic (Heads,

The purpose of the invention is to increase the degree of maintainability.

Figure shows a magnetic head, general view; figure 2 - magnto wire; on fig.Z - non-magnetic insert; Figs 4 and 5 show the shapes of the pole pieces; FIG. 6 shows a connecting line with a protruding part of polis tips of a constricted shape; in Fig. 7, the closing map-to-wire with a non-magnetic gap.

The magnetic head contains semi-blocks 1 and 2, half-cores 3, .winding 4, non-magnetic insert 5, pole pieces 6 with a working lock. with a bore 7, a closing magnetic circuit 8, clamping screws 9,

In the process of manufacturing the 1-s magnetic head, the ends of each half-core and the mating surfaces / given hour. These half blocks 1 or 2 turn-offs are jointly connected to obtain a plane. In order to ensure that after assembly and fastening, screws 9 half blocks 1 and 2 do not appear in the joint points for secondary gaps. The installation of the pole pieces 6 from the working side of the head can be performed both with and without protrusion from the insert 5, and the insert can also be installed with respect to the semi-blocks in a similar way. The size of the protrusion is well suited to be commensurate with the depth of the working gap in order to assess the degree of wear.

To increase the recording density, the pole tips can be made of a narrowed shape (FIG. 6), 243022 .2

the torus contributes to the localization of the field around the working gap 7. By reducing the size of the sticking magnetic circuit 8, an additional gap is created, 5 necessary for the recording heads. In this case, in the zone of the end interface with the half-hearts 3, the formation of both two additional gaps and one is possible. If necessary, the closing magnetic circuit 8 can be made of two parts, in this case an additional gap is formed between these parts (this gap can be located both in the common plane with the working gap and at an angle to it)

Claims (2)

Formula invented , A magnetic head consisting of two half blocks, each of which contains C-shaped half-cores with windings5 and also fixed screws of half blocks, is different. This is due to the fact that, in order to increase the degree of maintainability, a non-magnetic insert is inserted into it, located between two semi-blocks, as well as pole lugs with a working gap and a closing magnetic conductor, coupled with the end surfaces of the corresponding C-shaped nortycores parallel to the working gap of the pole lugs, and fixed in the transverse PE of the non-magnetic insert, 2 .. The head of the pop, 1, distinguished by the u-, schA and the fact that the pole pieces are made in the form of a removable C-shaped core with two working gaps on its opposite sides.
