Abstract

SE PRESENTA UN APARATO DE GRABACION Y REPRODUCCION DE INFORMACION MAGNETOOPTICO QUE TIENE UNA GUIA DE DESLIZAMIENTO FLOTANTE PARA SOPORTAR UNA CABEZA MAGNETICA PARA APLICAR UN CAMPO MAGNETICO MODULADO SEGUN LA INFORMACION A MEDIO DE GRABACION DE INFORMACION MAGNETOOPTICO. LA GUIA DE DESLIZAMIENTO FLOTANTE ESTA ADAPTADA DE TAL MODO QUE UN DISPOSITIVO DE RETRACCION LA RETRAIGA DEL MEDIO DE GRABACION SEGUN EL TIPO DE MEDIO, PARA QUE ASI LA GUIA DE DESLIZAMIENTO NO SE DAÑE EN LA GUIA DE DESLIZAMIENTO O EN EL MEDIO CARGADO EN EL APARATO.
