Description

one

The invention relates to the field of magnetic recording.

Blocks of magnetic heads are known that contain semi-blocks with half-cores arranged in them with windings 1. The half-cores in the half-blocks are arranged in parallel, and the terminals of the windings are soldered to the contact m of the plinth.

The disadvantage of this device is that it is impossible to reduce the distance between the magnetic fluids, and, consequently, to increase the transverse density of recording information on a magnetic tape.

Closest to the invention, the technical entity is a multi-track block of magnetic heads, the body of which consists of g, Euh half blocks with cutouts designed to accommodate half hearts with windings and inter-head screens 2. The winding leads pass through the holes in the lead blocks and are unsoldered on the contact plate.

The disadvantage of this unit is that the small distance between the magnetic cores, separated by shields in the rear gap area, contributes to the effect of one magnetic head on another. In addition, the conclusions of each winding of the half core must be passed through the corresponding

holes located under the half-heart. The fixing of the leads and their laying in this case is not made, which leads to their breakage when the block is subjected to vibrations or linear overloads, and consequently, the magnetic heads block is out of operation.

To increase the transverse information recording density and increase the isolation between the magnetic cores of the heads in the proposed

In the block, the semi-blocks are made in the form of a truncated arc sector, and the distance between the pairs of half-cores on the back gap section exceeds the distance between these pairs on the half-core segment, carrying

pole pieces.

FIG. 1 shows a cross section of the described unit with installed magnetic cores; in fig. 2 - section along the working gaps of the magnetic heads; in fig. 3- unit assembly.

The block consists of two semi-blocks 1, in which grooves 2 are made to accommodate the protruding parts of the windings 3. The terminals of the windings 4 are located along the half-cores 5 and are connected to terminals 6. The hull semi-blocks have the form of sector-shaped truncated along an arc as shown in FIG. 2. Semi-cores are installed in them at an angle a to each other, and the distance I between neighboring semi-cores in the rear gap is greater than the distance h between the same semi-cores in the region of the pole tips 7. In the semi-blocks there are also grooves 8 for installing inter-head screens. The semi-blocks are interconnected by screws 9, and inter-head screens 10 are installed in the slots 8.

Decreasing the distance between adjacent heads in the block in the area of the working gap increases the transverse information recording density.

Increasing the distance between the magnetic cores in the area of additional clearance reduces the interaction of magnetic heads and allows stacking the winding pins of each half core and improves their ease of installation, i.e., connection to the output terminals of the magnetic head unit.
