Abstract

Se proporciona un patrón de bits para un área de comienzo que permite que la reproducción de datos se realice aceptablemente cuando se incrementa la densidad de grabación de un disco óptico. Un disco óptico de acuerdo a la presente invención incluye pistas, cada una de las cuales se divide en una pluralidad de bloques de grabación. Cada uno de la pluralidad de bloques incluye un área de comienzo y un área de datos. En el área de comienzo, se puede grabar un patrón prescrito de bits de comienzo; y en el área de datos, se pueden grabar patrones de bits que tienen una pluralidad de longitudes de bits obtenidas al modular datos como un objetivo de grabación de acuerdo con una regla prescrita de modulación. En este disco óptico, al menos una de las frecuencias espaciales que corresponde a los patrones de bits que tiene la pluralidad de longitudes de bits es mayor que una frecuencia de corte. El patrón de bits de comienzo grabable en el área de datos incluye los patrones de bits que tienen la pluralidad de longitudes de bits, de los cuales se ha excluido el patrón de bits que corresponde a la frecuencia mayor que la frecuencia de corte de OTF.
