    • The present invention relates to a method and to an apparatus for manufacturing a record carrier having stored a content information in the form of a modulated bitstream 29 obtained from the content information by steps of encoding 21 and modulating 26. The record carrier has a number of dummy patterns at predetermined locations, allowing for the post-recording of secondary information, e.g. an individual code, whereby the secondary information is recorded by selectively modifying the dummy patterns. The method and apparatus according to the invention foresee that the modulated bitstream 29 with dummy patterns at the predetermined positions id obtained by inserting data word corresponding to the dummy patterns in a sequence of data words before the modulation takes place, so as to make sure that the dummy patterns are compliant with the modulation employed.
    • 本发明涉及一种用于制造记录载体的方法和装置,该记录载体具有通过编码21和调制26的步骤从内容信息获得的经调制比特流29形式的内容信息。记录载体具有多个 在预定位置处的虚拟图案,允许次要信息的后记录,例如 通过选择性地修改虚拟图案来记录辅助信息。 根据本发明的方法和装置预见,通过在调制之前将数据字的序列插入与伪图案相对应的数据字而获得的预定位置id处的伪图案的调制比特流29,以便确保 虚拟图案符合所采用的调制。
