Summary:PURPOSE: A file management method and a content recording/playback apparatus are provided to enable inter-content links to be maintained even when distributed content is recorded under a name that is different from the original content file name. CONSTITUTION: The content recording apparatus(130) comprises a package management information recording section(131), content file recording section(132), and link resolution information recording section(133). The package management information recording section(131) creates package management information for managing packages recorded on the recording medium(120) and records it on the recording medium(120). The content file recording section(132) records each content file of a content file group included in a package on the recording medium(120), and also creates content file group management information for managing these content file groups and records it on the recording medium(120). The link resolution information recording section(133) creates link resolution information for implementing links between content files that straddle packages and records it on the recording medium(120). The content playback apparatus(140) includes a content file acquisition section(141) and link resolution section(142). The content file acquisition section(141) receives a content playback command from the input apparatus(110), and acquires the specified file from the recording medium(120). When there is a link specification in a content file, the link resolution section(142) performs processing to specify the link destination content file based on link resolution information recorded on the recording medium(120). 패키지 관리 정보 기록부(131)는 패키지 단위로 배신되는 콘텐츠에 대하여, 패키지마다의 디렉토리를 작성하고, 디렉토리명과 패키지 식별자와의 관계를 나타내는 패키지 관리 화일을 작성한다. 콘텐츠 화일 기록부(132)는 콘텐츠 화일명과 해당 콘텐츠가 다른 콘텐츠로부터 링크되는 경우의 참조명과의 관계를 나타내는 콘텐츠 화일군 관리 화일을 작성한다. 링크 해결 정보 기록부(133)는 다른 패키지에 포함되는 콘텐츠를 나타내는 참조명과 다른 패키지의 패키지 식별자와의 대응 관계를 나타내는 링크 해결 화일을 작성한다. 재생 장치(140)의 링크 해결부(142)는 이들 화일 관리 정보를 이용하여 링크처 콘텐츠의 화일을 특정한다. 이에 따라, 배신한 콘텐츠가 본래의 콘텐츠 화일명과 상이한 명칭으로 기록되는 경우에서도, 콘텐츠 사이의 링크를 유지할 수 있다.
