DEVICE AND METHOD FOR PROVIDING MEDIA-RELATED PARAMETERS ON A MEDIUM AND FOR RETRIEVING SUCH PARAMETERS

摘要

The present invention relates to a record carrier, to a drive device for the record carrier, and to a method of providing at least one parameter that defines at least one characteristic of the record carrier on said record carrier. The at least one parameter is determined during a first access operation to the record carrier and is then written to a predetermined area of the record carrier by using a predetermined pattern of at least two different power levels. During a subsequent second access operation the at least one parameter is retrieved from the record carrier by detecting jitter values in the read-out signal. A simple and reliable measure for storing and retrieving these parameters on the record carrier is provided thereby.
