Multi-source cache management reproducing apparatus and method e.g. for blu ray disk-rom

The contents of a DVD video disc can be reproduced by use of reproduction control information realized by a Markup language. It is possible to hold a resource whose life period has elapsed in a cache memory (602) and use the resource again. Therefore, a data access manager (601), a file cache (621) which temporarily stores a plurality of resources and a navigation manager (including a filecache manager (603)) which processes management information used to manage a plurality of files held in the file cache (621) and controls the data access manager are provided. The filecache manager (603) registers a loaded resource into a first list if the resource lies within the life period and registers the resource into a second list and manages the same if the life period of the resource has expired.
