Abstract

EN UN DISPOSITIVO EXPLORADOR OPTICO PARA JUEGO CD SE EXTRAE LA SEÑAL (TE) DE ERROR DE VIA DE LA DIFERENCIA DE DOS FOTOSENSORES (ES) Y (FS). SE INTERRUMPE EL RAYO DE LUZ DEBIDO A UNOS EMPUJONES MECANICOS SOBRE EL JUEGO CD DESDE LA VIA DE DATOS A EXPLORAR, ASI QUE MEDIANTE INFORMACIONES CONTENIDAS EN UN SUBCODIGO PUEDEN CONDUCIRSE DE NUEVO SOBRE LA VIA DE DATOS CORRECTOS PERO PERJUDICAN Y PERTURBAN LA REPRODUCCION DEL SONIDO. EN UN GRABADOR OPTICO NO FORMATEADO NO EXISTE LA POSIBILIDAD DE CORRECCION. PARA PODER DIRIGIR RAPIDA Y REPETIDAMENTE Y DE FORMA SENCILLA UN CHORRO DE LUZ (8) SALIENDO DE LA VIA DE DATOS EXPLORADOS SOBRE LA VIA DE DATOS, SE CONTROLAN DICHOS RAYOS MEDIANTE UNA DIRECCION LOGICA (5) Y UNOS CONTADORES DE AVANCE Y RETROCESO (6). DEBIDO A LAS DISTINTAS VIAS DE DATOS LOS CHORROS DE LUZ (8) SE DESVIAN HACIA LA DERECHA O HACIA LA IZQUIERDA A PARTIR DE LAS VIAS EXPLORADAS. DEL INDICADOR DEL CONTADOR SE EXTRE LA SEÑAL DE CORRECCION PARA EL CIRCUITO REGULADOR DE VIA. JUEGO CD, JUEGODE VIDEO Y PLACA, JUEGO DRAW - DISCO SON APARATOS MAGNETO OPTICOS.
