Abstract

<B>"SISTEMA, APARELHO, MéTODO DE CóPIA E MEIO DE GRAVAçãO"<D> O sistema de cópia de dados da presente invenção inclui um aparelho de cópia de dados para copiar dados gravados em um primeiro meio de gravação para um segundo meio de gravação. O aparelho de cópia de dados inclui: uma seção de leitura de dados para ler os dados a partir do primeiro meio de gravação; uma seção de controle de modificação de dados para controlar modificação dos dados em conformidade com a informação de controle de modificação, a informação de controle de modificação sendo provida para controlar a modificação dos dados; e uma seção de escrita de dados para escrever uma saída da seção de controle de modificação de dados para o segundo meio de gravação. A informação de controle de modificação inclui um indicador de permissão de cópia que indica se a cópia dos dados é permitida; um indicador de controle de qualidade para controlar a qualidade de dados modificados que são obtidos através da modificação dos dados; e um indicador de controle de cobrança para controlar a cobrança da cópia dos dados. A seção de controle de modificação de dados determina se é a cobrança é necessária para a cópia dos dados em conformidade com o indicador de controle de cobrança. Quando a cobrança é necessária, a seção de controle de modificação de dados controla a modificação dos dados em conformidade com o indicador de permissão de cópia e com o indicador de controle de qualidade, depois de confirmar que a cobrança foi efetuada pelo aparelho de cobrança. Quando a cobrança não é necessária, a seção de controle de modificação de dados controla a modificação dos dados em conformidade com o indicador de permissão de cópia e com o indicador de controle de qualidade, sem confirmar que a cobrança foi efetuada pelo aparelho de cobrança.
