Abstract
A data structure is printed using infra-red ink. The data structure includes a two dimensional array of data blocks. Each adjacent pair of data blocks is separated by a gap and each of the data blocks has a data region holding encoded data. Each data region is confined by clock-marks and borders to facilitate location of the data region and recovery of data from within the data region. Each of the data blocks is associated with targets to facilitate location of its data region.
