Abstract
PROCESO Y SISTEMA DE GRABACION MAGNETICA DE INFORMACION SOBRE VARIAS PISTAS PARALELAS SEGUN EL CUAL LA GRABACION DE UNA INFORMACION SOBRE UNA PISTA SE HACE POR INDUCCION DE UN CAMPO MAGNETICO DE UN SENTIDO DETERMINADO EN UNA ZONA DE ESTA PISTA Y QUE DURANTE ESTA GRABACION, SE INDUCE UN CAMPO MAGNETICO DE SENTIDO INVERSO EN ZONAS DE LAS PISTAS VECINAS. PARA ESTO, EL ARROLLAMIENTO (L0,L1,L2) DE CADA CABEZA ESTA ACOPLADO AL MENOS A LOS ARROLLAMIENTOS (LO, L1, L2) DE SUS CABEZAS VECINAS. UNA CORRIENTE DE CONTROL TRANSMITIDA A DICHA CABEZA DA ASI LUGAR A AL MENOS UNA CORRIENTE DERIVADA HACIA LAS CABEZAS VECINAS,. APLICACION CORRECCION DE LA DIAFONIA DE LA LECTURA DE GRABACIONES MAGNETICAS DE ALTA DENSIDAD.
