Abstract
МНОГОДОРОЖЕЧНАЯ ТОНКОПЛЕНОЧНАЯ МАГНИТНАЯ ГОЛОВКА, содержаща тонкопленочные одноканальные секции, одна из которых закреплена на подложке, а рабочие зазоры одноканальных секций расположены в одной плоскости, отл. ичающа с тем, что, с целью повышени поперечной плотности записи, в ней одноканальные секции расположены одна над другой и разделены между собой экранирующим магнитным и .диэлектрическим сло ми. 6 в WMULTI-TRAWN THIN-FILM MAGNETIC HEAD, containing thin-film single-channel sections, one of which is fixed on the substrate, and the working gaps of single-channel sections are located in the same plane, exc. It is due to the fact that, in order to increase the transverse recording density, in it single-channel sections are located one above the other and are separated from each other by shielding magnetic and dielectric layers. 6 in W

When recording information through the drawing, the single-channel-conducting layer 1 is shown in the form of thin-film sections of the multi-track thin-night winding of each of the single-channel film magnetic head, common sections 2 are passed through the electric field, to create a recording field in the working section of the multi-track 2. At the same time, in the sub-magnetic head contains an under-night oil-milling unit 6
