Abstract

"PORTADOR DE GRAVAçãO, DISPOSITIVO DE GRAVAçãO E/OU REPRODUçãO, E, MéTODO PARA FABRICAR UM PORTADOR DE GRAVAçãO". Um portador de gravação (1) é descrito que tem uma trilha de servo (4) indicando uma trilha de informação (9) pretendida para gravar blocos de informação, cuja trilha de servo (4) tem uma variação de um parâmetro físico, uma denominada oscilação. A oscilação é modulada para codificar informação de portador de gravação, tal como endereços. A trilha de servo é subdividida em partes moduladas nas quais a freq³ência e/ou fase da variação se desvia da freq³ência de oscilação, e partes não moduladas. A inclinação da oscilação é substancialmente contínua em transições entre as partes moduladas e não moduladas usando oscilações (25, 26, 27, 28) começando nos máximos ou mínimos da oscilação na primeira parte das partes moduladas.
