Abstract

A record carrier for storing at least one stream of linked content cells thereon, which linking is performed based on navigation data. The record carrier includes modified navigation data and/or a stream arrangement of at least one stream of linked content cells, so that an access of the at least one stream of linked content cells on the record carrier under consideration of the navigation data is not disturbed, whereas a generally linear access of the at least one stream of linked content cells on the record carrier is disturbed.
