摘要：
When updating a local copy of metadata, first change history data of metadata are read from an optical storage medium. Second change history data of the metadata are read from a local storage of an optical storage medium playback and/or recording device. If the first and second change history data are different a change attribute is read from the optical storage medium and an update operation of the metadata stored in the local storage or an update operation in the optical storage medium is determined depending on the change attribute.
