Coded data pattern having redundantly-encoded orientation
First Claim
1. A substrate having a coded data pattern disposed on a surface thereof, said coded data pattern comprising a plurality of discrete circular target features defining a grid, said grid comprising a plurality of tags with neighboring tags sharing target features, each tag comprising respective tag data encoded by a plurality of macrodot data elements contained in each tag, wherein said macrodot data elements encode:
- a plurality of Reed-Solomon symbols, wherein a set of said symbols define a Reed-Solomon codeword representing at least some of said tag data; and
an orientation of a layout of said tag data,wherein said orientation is encoded a plurality of times in each tag.

Abstract
A substrate having a coded data pattern disposed on a surface thereof. The coded data pattern comprises a plurality of target features defining a grid. The grid comprises a plurality of tags with neighboring tags sharing target features. Each tag comprises respective tag data encoded by a plurality of macrodot data elements contained in each tag. The macrodot data elements encode: a plurality of Reed-Solomon symbols, wherein a set of the symbols define a Reed-Solomon codeword; and an orientation of a layout of the tag data. The orientation is encoded a plurality of times in each tag.
