The quiet zone is an area around the code that must be free of any marking or any physical characteristics that the reader might interpret as markings. The required size of the quiet zone depends on the reader and marking technology used, but should never be narrower than the width of one cell.
The finder pattern, or "L pattern", is made up of one column and one row, both consisting of all "on" cells, that meet in one corner of the code. The finder pattern is used by the reader to locate the code and determine its physical size.
The clocking pattern is made up of one column and one row on sides of the code opposite those of the L pattern. The clocking pattern consists of alternating "on" and "off" cells, and is used by the reader to gauge the size of a cell.
The data region is made up of all but the peripheral columns and rows of the code. It is in the portion of the code that "on" and "off" cells are used to encrypt the desired character string.

DATAMATRIX CODES CAN BE RECTANGULAR AS WELL AS SQUARE

Rectangular Code

Rectangular codes can be particularly useful when the area on the part available for marking is limited or oddly shaped.
