Storing data holographically presents a number of coding challenges. Firstly, identifying the correct constraints creates the need for two-dimensional and even three-dimensional modulation codes. Secondly, the noise produces particular two-dimensional error patterns, requiring special configurations of the error-correcting codes. We present a menu of possible modulation coding and error-correction coding techniques to improve the reliability of data stored holographically.
