File management method and content recording/playback apparatus

摘要

A package management information recording section 131 creates a directory for each package for content distributed in package units, and creates a package management file indicating the relationship between a directory name and package identifier. A content file recording section 132 creates a content file group management file indicating the relationship between a content file name and a reference name when that content is linked from other content. A link resolution information recording section 133 creates a link resolution file indicating the correspondence between a reference name indicating content included in another package and the package identifier of the other package. A link resolution section 142 of a content playback apparatus 140 specifies a link destination content file using these items of file management information. By this means, a link between contents can be maintained even when distributed content is recorded with a name different from the original content file name.
