  • Visual watermark in both data area and inner-ring of record carrier
    Patent number: 7826636
    Abstract: A record carrier including a data area for storing data in the form of marks, in which the data is encoded by means of a channel code, wherein a parameter of the channel code is controlled so as to introduce a predetermined run length distribution in the marks on the record carrier, thereby introducing first information relating to a watermark, and a non-data area comprising second information relating to a watermark, the first and the second information forming the watermark. This watermark, extending over the data-area and the inner-ring area and/or the outer-ring area, can be used for checking the authenticity of the record carrier and/or the recordings made on this record carrier.

  • Record carrier with watermark
    Patent number: 7801327
    Abstract: A record carrier includes a pattern of substantially parallel tracks for storing data in the form of marks, in which the data is encoded by a channel code. A watermark is provided by controlling the parameter of the channel code so as to introduce a predetermined run length distribution in the marks on the record carrier. Brightness differences are caused by introducing this run length distribution.
