Track writing with radial error offset correction

The present invention relates to a method and apparatus for writing data on a record carrier (1) by using a radiation beam, wherein at least one of a writing power and an asymmetry of data written on the record carrier (1) is determined and a radial error offset, applied to the radiation beam with r...

Summary:The present invention relates to a method and apparatus for writing data on a record carrier (1) by using a radiation beam, wherein at least one of a writing power and an asymmetry of data written on the record carrier (1) is determined and a radial error offset, applied to the radiation beam with respect to a writing track of the record carrier (1), is controlled in response to at least one of the determined writing power and the determined asymmetry. Thereby, the radial error offset can be linked to at least one of the applied writing power and the obtained asymmetry of the written data, and can thus be altered before or during writing to maintain reasonable tracking in cases where writing is done on record carriers with variable radial error offset.
