Abstract

Dispozitiv de pozitionare pentru capul de înregistrare si citire la discuri magnetice, caracterizat prin aceea ca printr-un substrat izolant (1) în forma de placa, care este suportul a cel putin unei bobine de inductie plana (2), printr-o axa de rotatie (3) de care s-a fixat substratul cu planul sau perpendicular pe axa de rotatie, apoi prin cel putin un agregat de înregistrare si citire (B), care este fixat pe aceeasi axa de rotatie (B) si prin cel putin un ansamblu magnetic (A) care este prevazut, în raport cu substratul în asa fel încît substratul poate fi oscilat în jurul axei de rotatie (3) prin trecerea curentului în bobina (2).
