Abstract
Disclosed is a method for decoding data that is encoded on a medium in a two-dimensional arrangement of code symbol marks (). According to said method, orientation symbol marks () are disposed in several rows and several columns such that a grid of row centerlines and column centerlines is adjusted to the read orientation symbol marks () by determining a step width for the rows and the columns while read code symbol marks () are assigned to one respective point of intersection of the adjusted grid, said point of intersection being linkable to a defined piece of data. The step width of the rows is different from the step width of the columns, and a relative orientation of the two-dimensional arrangement of code symbol marks () is determined from the ratio between the two step widths. A data range () that is used for code symbol marks () is determined from a reference symbol mark (). The code symbol marks () and the orientation symbol marks () are distinguished based on a characteristic, distinct graphic design and are allocated, respectively.
