Abstract

"APARELHO E MéTODO PARA TESTAR RESISTêNCIA DE DISCO óPTICO" São revelados um aparelho e método para testar resistência de um disco óptico, pelo que a confiabilidade do teste é aumentada. O método inclui fixar o disco óptico em uma chapa de rotação, e girar o disco óptico juntamente com a chapa de rotação, fornecer uma pressão predeterminada ao dispositivo de arranhar, enquanto o disco óptico gira por um número predeterminado de voltas de rotação, de modo a produzir um arranhão em uma superfície do disco óptico, resultando de um contato com o dispositivo de arranhar, e determinar a resistência do disco óptico com base no arranhão produzido na superfície do disco óptico.
