Abstract
A decision section decides whether or not contents recorded on a HDD satisfy a predetermined condition based on contents management information indicating an attribute of the contents and an operation exerted on the contents. If contents satisfying the condition have not been compressed by a contents compress processing section, the contents are compressed by the contents compress processing section. If having been compressed, the contents are deleted by a contents delete processing section.
