Abstract

The invention relates to the accumulation of information. The purpose of the invention is to reduce energy consumption. The stepping motor 6 provides a stepping movement of a magnetic recording medium consisting of a non-magnetic base 3 on which elastic hairs 2 made of a magnetically hard material are cantilevered. With each step movement, the magnetic recording medium is displaced by a distance equal to the distance between hairs 2. At the end of the step movement, hairs 2 are set under the working surfaces of the recording magnetic heads 1. At the same time, the hairs 2 under the working surfaces of the heads 1 are bent to the surface of the base 3 magnetic recording media. The information is recorded by applying pulses to the corresponding heads 1 upon the completion of the step movement of the magnetic recording medium. When this happens, only those hairs 2 that are under the working surfaces of the respective heads 1 are magnetized. In the next step movements, hairs 2 come out from under the working surfaces of the heads 1. In this case, the nonmagnetized questions 2 are straightened and the magnetized hairs 2 acquire a loop-like shape, ensuring the creation of a different color in relation to the general background, created by the color of the warp 3 and the ends of non-magnetised hairs 2. 2 cf f-crystals, 3 ill.

Claims (2)

Claim 1. The method of magnetic recording of information, which consists in the selective action of a magnetic needle on the working layer of the carrier, consisting of elastic hairs made of hard magnetic material, cantilever mounted on the surface of a non-magnetic base and having a different color of the side and end surfaces, characterized in that, in order to reduce energy consumption and improve the quality of recording, the magnetic field gradient is oriented in the direction of movement of the carrier parallel to its plane, and the elastic hairs per Magnetization units are bent to the surface of a nonmagnetic base in the direction coinciding with the direction of the magnetic field gradient. 2. A device for magnetic recording of information, containing 5 magnetic recording heads arranged in two rows against the hairs made of hard magnetic material and mounted cantilever on the first surface of the non-magnetic axis of the magnetic recording medium having perforations in which the teeth of the gear drum of the stepper motor are located moving and erasing magnetic heads, characterized in that, in order to reduce energy consumption and improve recording quality, diamagnetic plasmas are introduced into it tines installed on the side of the second surface of the non-magnetic base of the magnetic recording medium against the erasing magnetic heads and against the recording magnetic heads made with dividing magnetic screens and staggered in two rows arranged perpendicular to the direction of stepwise movement of the non-magnetic base of the magnetic recording medium parallel to the gradient 10 a recording magnetic field of each recording magnetic head, the working surfaces of the recording magnetic heads being laid at a distance of the thickness of the hairs from the first 15 surface of the non-magnetic base of the magnetic recording medium, located at a distance of double the thickness of the hairs from the working surfaces of the erasing magnetic heads.
