Abstract

UNA UNIDAD DE CD-ROM TIENE N GAMAS SELECCIONABLES DE VELOCIDAD Y, DENTRO DE CADA GAMA, VELOCIDADES DE ROTACION QUE DISMINUYEN DE MANERA LINEAL DESDE EL SECTOR EXTERIOR AL INTERIOR, A CONDICION DE QUE SE REDUZCA AUTOMATICAMENTE LA VELOCIDAD DE ROTACION EN CASO DE RESULTADOS NEGATIVOS EN LA LECTURA. UNOS MEDIOS DE CONTROL CONMUTAN LA UNIDAD CD-ROM A UNA ESCALA INFERIOR DE VELOCIDAD CUANDO SE SUPERA UN NIVEL PREDETERMINADO DE RUIDO Y/O OCURREN VIBRACIONES.
