Abstract

"MEIO, APARELHO E MéTODO DE GRAVAçãO DE INFORMAçãO". A presente invenção refere-se a um meio de gravação de informação que compreende: uma primeira camada de gravação para gravação ali de uma primeira informação a qual é pelo menos uma porção de uma informação de gravação; e uma ou uma pluralidade de segundas camadas de gravação, as quais são dispostas na referida primeira camada de gravação, para gravação ali de uma segunda informação a qual é pelo menos uma outra porção da informação de gravação, onde cada uma das referidas segundas camadas de gravação tem uma área predeterminada na qual uma calibração de potência é realizada para a detecção de uma potência de gravação ótima de luz de laser para gravação, a qual é transmitida através da referida primeira camada de gravação e de outras camadas das referidas segundas camadas de gravação, a referida primeira camada de gravação, as outras camadas das referidas segundas camadas de gravação e cada referida das referidas segundas camadas de gravação disposta nesta ordem, como visto a partir de um lado de irradiação da luz de laser, e em uma área de faceamento, a qual se volta para a área predeterminada, nas outras camadas das referidas segundas camadas de gravação e da referida primeira camada de gravação, pela formação de cavidades gravadas em relevo, a transmitância de luz da área de faceamento é tornada mais próxima para (i) transmitância de luz sob uma hipótese de (i-1) as cavidades gravadas em relevo não serem formadas e de (i-2) as outras camadas e a referida primeira camada de gravação já estarem gravadas, se comparado com (ii) transmitância de luz sob uma hipótese de (ii-1) as cavidades gravadas em relevo não estarem formadas e de (ii-2) as outras camadas e a primeira camada de gravação não estarem gravadas.
