Abstract
EN APARATO OPTICOS MAGNETICOS DE REGISTRO Y REPRODUCCION SE PREVE UN ELECTROIMAN PARA PODER CAMBIAR LA MAGNETIZACION DE LA CAPA OPTICA MAGNETICA DE LA PLACA OPTICA MAGNETICA EN DEPENDENCIA DE LOS BITS A MEMORIZAR. PARA OBTENER UN CAMBIO DE MAGNETIZACION RAPIDO Y SEGURO, SE HA PUESTO UNA BOBINA (S) COMPUESTA DE DOS BOBINADOS (W1, W2) CONECTADAS EN LINEA QUE ESTA BOBINADAS EN SENTIDO CONTRARIO. EL PUNTO DE CONEXION COMUN DE AMBOS BOBINADOS (W1, W2) ESTA DISPUESTO EN UNA TENSION DE ALIMENTACION (U) MEDIANTE UNA CONEXION EN LINEA DE UNA INDUCTIVIDAD (L) Y UNA FUENTE DE ENERGIA (Q). LA CONEXION LIBRE (B1) DE UNO DE LOS BOBINADOS (W1) ESTA DISPUESTO POTENCIAL DE REFERENCIA POR UN PRIMER DIODO (D1) Y UNA CONEXION EN PARALELO CONECTADA EN LINEA DE UNA CAPACIDAD (C) Y UN DIODO ZENER (Z). LA CONEXION LIBRE (B2) DEL OTRO BOBINADO (W2) ESTA CONECTADO MEDIANTE UN SEGUNDO DIODO (D2) CON EL PUNTO DE CONEXION COMUN DEL PRIMER DIODO (D1) Y LA CONEXION EN PARALELO. LA CONEXION LIBRE (B1) DE UNO DE LOS BOBINAS (W1) ESTA CONECTADA MEDIANTE UN PRIMER INTERRUPTOR (S2) DE CONTROL Y LA CONEXION LIBRE (B2) DEL OTRO BOBINADO (W2) MEDIANTE UN SEGUNDO INTERRUPTOR DE CONTROL (S2) CON EL POTENCIAL DE REFERENCIA. PARA REGISTRAR DATOS SE ABREN O CIERREN LOS INTERRUPTORES DE CONTROL (S1, S2) EN FASES CONTRARIAS POR UNA CONEXION DE MANDO (AS) EN DEPENDENCIA DE LOS BITS A MEMORIZAR. APARATOS DE REGISTRO MAGNETICOS Y OPTICO MAGNETICOS.
