Abstract

SE DESCRIBE UN PROCEDIMIENTO PARA EL SEGUIMIENTO DE UNA PISTA EN UN APARATO DE CINTA MAGNETICA, INDICADOS PREFERIBLEMENTE PARA APARATOS DE R-DAT. ANTES DE LA REPRODUCCION DEL NIVEL DE LAS SEÑALES DEL SEGUIMIENTO DE HUELLA EN SALIDAS-AMPLIFICADORAS DE CABEZA SE MIDE DE FORMA ESCALONADA EL CAMBIO DE LA FASE DE EMPUJE DE LA BANDA, GENERANDO Y ALMACENANDO UNA DIFERENCIA EN UNA DIMENSION DE CORRECTURA Y SIRVE, EN UNA REPRODUCCION POSTERIOR, PARA CORREGIR LA DIMENSION DE AJUSTE PARA LA POSICION MEDIA DE LA HUELLA. UNA REPRODUCCION DE LA HUELLA MEDIA SE GARANTIZA CUANDO ESTA PUESTO EN FUNCIONAMIENTO EL APARATO Y SE ORIGINAN NIVELES DIFERENTES, QUE PUEDE SER PRODUCTO DE UN MAL AJUSTE DE LAS PIEZAS, DE UN MAL CERRADO O DE LA SUCIEDAD DE LAS CABEZAS.
