Abstract

The invention relates to methods for making the working surface of an auto-tracking magnetic head and improves the quality of the magnetic head. The working surface is treated with abrasive tape 1, while the magnetic head rotates in the drum of video recorder 2 and performs transverse movements when a sinusoidal control voltage is applied to its piezoelectric transducer 4, the frequency of which is less than resonant, and the amplitude is selected according to the range of movement of the magnetic head operation. 1 il.

Description

The invention relates to an information storage technique and can be used in the design of magnetic heads for video recording.
The purpose of the invention is to improve the quality of manufacture by increasing the recoil of the magnetic head.
The drawing shows the processing circuit in the manufacture of the magnetic head auto tracking.
An apparatus for carrying out the method comprises an abrasive belt 1, a guide drum of the video recorder 2, a magnetic core 3 of the magnetic head, a piezo transducer 4.
In the manufacture of a magnetic head, the processing of inclined planes on the working surface is performed by known methods. Further processing of the working surface in the part where it has the shape of an ellipsoid of rotation is produced
in the following way. The magnetic head is installed, for example, on the process video recorder in the working position and connected to the electronic control unit of the piezoelectric transducer 4. An abrasive tape 1 is used, the base of which is the same as that of the magnetic tape, i.e. has the same mechanical properties. At the same time, in addition to respecting the identity of the mechanical properties of the tapes, they provide the same conditions for its installation in a tape drive mechanism. In the processing mode of the working surface, sinus-diaal oscillations are applied to the auto-tracking magnetic head, which do not create large accelerations, leading to significant dynamic loads on the head. In order to obtain the shape of the working surface, which corresponds to the maximum specified, which provides the greatest return, the amplitude of oscillations is chosen the same as takes place during the operation of the head in the video arc (L
