Abstract
DISPOSITIVO PARA INSCRIBIR INFORMACION EN UN DISCO DE REGISTRO, PROVISTO DE UNA CAPA SENSIBLE A LA RADIACION Y AREAS DE INFORMACION EN FORMA ESPIRAL O CONCENTRICA, LEGIBLE POR MEDIOS OPTICOS. UNA FUENTE DE LUZ (15) PROYECTA SOBRE EL DISCO (4) UN HAZ (16A) PARA INSCRIBIR LA INFORMACION Y UN HAZ SEGUIDOR (16A) PARA DETECTAR DICHA INFORMACION. LOS DOTODIODOS (27, 50) RECOGEN LA REFLEXION DE LOS HACES (16A, 16B), Y POR MEDIO DE FILTROS PASABANDA SEPARAN DOS SEÑALES DE RELOJ, QUE SINCRONIZAN EL PROCESO DE ESCRITURA Y EL DE LECTURA. DURANTE LA LECTURA SE CIERRA EL CONMUTADOR (53) Y SE AJUSTA EL DISPOSITIVO DE RETARDO (51).
