    Thanks a lot for all the help. I think the datamatrix barcode would be
    ideal for my requirement. I need to encode the azimuth circle on my
    telescope. So I dont have to worry about scalability, it is never
    going to be more than 3600( for 0.1 deg accuracy). What size
    datamatrix code would I require, preferably rectangular. Secondly,
    since my application requires my telescope to be portable, I cant
    carry a computer around. Is there any circuit which would just read
    the output of the barcode reader and display it on a digital readout.
    Thirdly, since each of the barcodes would be just around 0.2mm apart,
    will the reader be able to read them(distance between reader and
    barcode is not an issue). Or do I have to cover the adjacent barcodes
    and leave a slit of just 0.2mm for the readers view. Comments, advice
    and suggestions please. Thanks a lot.
