SCANNER, METHOD FOR CREATING AN ELECTRONIC REPRODUCTION OF A TWO-DIMENSIONAL INFORMATION PATTERN, AND DATA CARRIER

摘要

The invention is directed to a scanner (10) for scanning an at least two- dimensional information pattern (12) provided on a data carrier (14), wherein the scanner comprises: driving means (16) for rotating the data carrier (14); an optical pick up unit (18) for scanning the at least two-dimensional information pattern (12) while the data carrier (14) is rotated; and memory means (20) for storing an electronic reproduction of the at least two- dimensional information pattern (12). Furthermore, the invention is directed to a method for creating an electronic reproduction of an at least two-dimensional information pattern (12) provided on a data carrier (14), the method comprising the following steps: rotating the data carrier (14); picking up the at least two-dimensional information pattern (12) while rotating the data carrier (14); and storing an electronic reproduction of the at least two-dimensional information pattern (12). The invention is also directed to a data carrier (14) intended to be read by a scanner (10) while being rotated, the data carrier (14) comprising: a radial reference plane (32) for aligning a plurality of start addresses associated to a plurality of tracks (34); and an information layer (38) comprising or being adapted to receive an at least two-dimensional information pattern (12).
