Abstract

"DISPOSITIVO DE DISCO óTICO". Para ser posicionado corretamente sobre uma plataforma giratória, um disco ótico composto de dois discos óticos colados um ao outro, independentemente da intensidade na qual eles são unidos um ao outro. O dispositivo inclui a plataforma giratória, sobre a qual o disco ótico é colocado, uma parte de fixação do disco sobre a qual é encaixado um orifício de montagem do disco ótico, e um elemento de retenção, o qual é posicionado sobre parte da superfície circunferencial na parte de fixação do disco, é livre para se movimentar na direção radial da parte de fixação do disco, e é impelido radialmente para fora. O elemento de retenção é formado em um formato de uma montanha por duas faces inclinadas e as faces inclinadas se confluem. A ponta é chanfrada em uma forma tal que a ponta forma um contato de superfície com o disco ótico quando o disco ótico é montado na plataforma giratória.
