Abstract
The invention relates to a method for personalizing a recordable data storage medium. At least one property of a non-recorded data area is modified in the same way as if data were recorded thereby creating determined patterns on or in the data storage medium. The property to modify may be an optical property rendering the determined patterns visible to human eyes. The invention further relates to a data storage medium comprising the mentioned determined patterns and to a device for transfering determined patterns on or in a data storage medium.
Claims11
A method for personalizing a recordable data storage medium comprising the steps of:
- providing a recordable data storage medium having a data storage area that includes an already recorded data area and a non recorded data area, said already recorded and non recorded data areas having different optical properties caused by recording of data;
- and
- modifying a property of said non recorded data area to create determined patterns on said recordable data storage medium using a same modification process used to record data in said already recorded data area, whereby personalized visual information is added to said recordable data storage medium.
A device for transferring determined patterns on or in a recordable data storage medium comprising:
- a recordable data storage medium having a data storage area including an already recorded data area and a non recorded data area, said already recorded and non recorded data areas having different optical properties caused by recording of data;
- means for modifying a property of said non recorded data area to create determined patterns on said recordable data storage medium by using addresses associated with selected preformatted groove portions on or within said recordable data storage medium.
