First Claim
1. A data structure encoded on a surface of an object, said data structure comprising a plurality of block data regions, each of said block data regions including:
- an encoded data region containing data in encoded form;
a clock mark structure located adjacent a first peripheral portion of said encoded data region; and
a target structure located adjacent said clock mark structure;
wherein each of said block data regions further includes an orientation data structure indicative of an orientation of said data structure.

Abstract
A data structure encoded on a surface of an object, and a method of generating such a data structure. The data structure includes a plurality of block data regions. Each of the block regions includes an encoded data region containing data in encoded form, a clock mark structure located adjacent a first peripheral portion of the encoded data region, and a target structure located adjacent the clock mark structure. Each of the block data regions further includes an orientation data structure indicative of an orientation of the data structure.

8. A method of decoding a data structure encoded on a surface of an object, said data structure comprising a plurality of block data regions, each of said block data regions including:
-
an encoded data region containing encoded data;
a series of clock mark structures located adjacent said encoded data region; and
a plurality of identifiable target structures located adjacent said series of clock mark structures;
the method comprising the steps of;
(a) scanning said data structure;
(b) locating the start of said data structure;
(c) locating said target structures and determining the orientation of said target structures;
(d) locating said clock mark structures based on the position of said target structures;
(e) utilising said clock mark structures to determine an expected location of bit data of said encoded data region; and
(f) determining a data value for each bit of said bit data. - View Dependent Claims (9, 10)
