Abstract

CABEZA MAGNETICA DE PISTA MULTIPLE A USAR CON UNA CINTA MAGNETICA EN UN SISTEMA DE GRABACION Y REPRODUCCION QUE INCLUYE AL MENOS DOS PUNTAS DE CABEZA MAGNETICA DISPUESTAS DE FORMA CONTIGUA Y MOVIBLES CON RESPECTO A LA CINTA MAGNETICA. LAS PUNTAS DE LA CABEZA INCLUYEN UNA PUNTA DE CABEZA DELANTERA PARA UN CONTACTO DESLIZANTE INICIAL CON LA CINTA MAGNETICA Y UNA PUNTA DE CABEZA COLGANTE PARA UN POSTERIOR CONTACTO DESLIZANTE CON LA CINTA MAGNETICA. LA PUNTA DE LA CABEZA DELANTERA ESTA HECHA DE MATERIAL CUYA RESISTENCIA AL DESGASTE ES MAYOR QUE LA DEL MATERIAL DEL QUE ESTA HECHO ESTA CABEZA DE PUNTA COLGANTE. LAS PUNTAS DE LA CABEZA SE MANTIENEN EN BUEN CONTACTO DESLIZANTE CON LA CINTA MAGNETICA PARA CONSEGUIR MEJORES CARACTERISTICAS DE GRABACION Y REPRODUCCION.
