Abstract

EL IMAN DE ESCRITURA DE UN DISPOSITIVO DE GRABACION Y DE REPRODUCCION MAGNETO-OPTICO SE PUEDE LLEGAR A CALENTAR TANTO DURANTE EL FUNCIONAMIENTO QUE DEBE SER ENFRIADO. PARA ASEGURARSE QUE SE OBTIENE UN ENFRIADO EFECTIVO, EL CUERPO REFRIGERANTE, QUE LLEVA EL IMAN DE ESCRITURA (M), SE COBRA ENCIMA O DEBAJO DE UN PORTADOR DEL REGISTRO GIRATORIO (DISCO COMPACTO). HAY COLOCADAS UNAS VARILLAS REFRIGERANTES (R) QUE SE MUEVEN EN EL SENTIDO DE ROTACION DEL PORTADOR DEL REGISTRO (DISCO COMPACTO) ES AL MENOS UN LADO DEL CUERPO REFRIGERANTE. EL CUERPO REFRIGERANTE ES ADECUADO, POR EJEMPLO, PARA DISPOSITIVOS DE GRABACION Y DE REPRODUCCION MAGNETO-OPTICOS.
