Abstract

SE DESCRIBEN UNOS MEDIOS MAGNETICOS DE GRABACION Y UNOS SISTEMAS DE GRABACION MAGNETICA QUE EMPLEAN DICHOS MEDIOS, LOS CUALES INCORPORAN UN RETICULO OPTICO DE TRANSMISION DE LUZ AL MENOS SUSTANCIALMENTE COEXTENSO CON EL AREA DE GRABACION MAGNETICA. UN SEGUNDO RETICULO OPTICO DE TRANSMISION DE LUZ ESTA ASOCIADO CON EL TRANSDUCTOR MAGNETICO O CABEZA DE LECTURA/ESCRITURA. LA LUZ TRANSMITIDA A TRAVES DE AMBOS RETICULOS PRODUCE UN DIAGRAMA DE MUARE, LOS CAMBIOS EN EL CUAL, RESULTANTES DE CAMBIOS EN LA ALINEACION DE LOS RETICULOS COMO CONSECUENCIA DEL MOVIMIENTO DE LA CABEZA LECTORA/GRABADORA EN RELACION A LOS MEDIOS, SE EMPLEAN PARA SUMINISTRAR INFORMACION SERVOMECANICA PARA MANTENER EL TRANSDUCTOR MAGNETICO ALINEADO CON LA PISTA MAGNETICA. EMPLEANDO ESTOS MEDIOS Y SISTEMAS PUEDE OBTENERSE UNA CAPACIDAD MAYOR DE GRABACION MAGNETICA, PUESTO QUE NO SE EMPLEA NINGUNA DE LAS AREAS DE GRABACION PARA INFORMACION SERVO.
