Abstract

EN UN DISPOSITIVO DE GRABACION Y/O REPRODUCCION MAGNETOOPTICO, UNA RUEDA (R1) UNIDA A UN PRIMER BRAZO PIVOTANTE (AR1) PRESIONA A LA PORTADORA DE REGISTRO, UN DISCO (CD), CONTRA UNA RUEDA CONTADORA (R1). LA SUPERFICIE INFERIOR DEL DISCO (CD) ES EXPLORADA POR UN EXPLORADOR OPTICO. UN ELECTROIMAN (M) COLOCADO INMEDIATAMENTE ENCIMA DE LA SUPERFICIE SUPERIOR DEL DISCO (CD) INVIERTE LA MAGNETIZACION DEL DISCO (CD). PARA EVITAR QUE EL IMAN (M) RAYE EL DISCO (CD) DURANTE LA INTRODUCCION O EXTRACCION DEL DISCO, SE PIVOTA EL PRIMER BRAZO (AR1) HACIA ARRIBA. SE FIJA EL IMAN (M) A UN SEGUNDO BRAZO (AR2) QUE PUEDE PIVOTAR ALREDEDOR DE UN EJE (A2) Y QUE DESCANSA SOBRE UN BRAZO (AR3) DE UNA PALANCA (H). EL OTRO BRAZO (AR4) DE LA PALANCA (H), QUE ESTA FIJADO A UN EJE (A3) SOBRE EL PRIMER BRAZO (AR1), GOLPEA UN TOPE LIMITADOR (A5). CUANDO SE PIVOTA EL PRIMER BRAZO (AR1) HACIA ARRIBA, EL BRAZO (AR3) DE LA PALANCA (H) EMPUJA AL SEGUNDO BRAZO (A2) HACIA ARRIBA, JUNTO CON EL IMAN Y LO LEVANTA SEPARANDOLO DEL DISCO. A MEDIDA QUE EL OTRO BRAZO (AR4) DE LA PALANCA (H) GOLPEA EL TOPE LIMITADOR (A5), LA PALANCA (H) GIRA ALREDEDOR DE SU EJE (A3), CON LO QUE EL SEGUNDO BRAZO (AR2), JUNTO CON EL ELECTROIMAN (M), PIVOTA SEPARANDOSE AUN MAS DEL DISCO (CD)
