The demand for the data pages in holographic data storage is balanced . i. e. the page contains the same number of 0's and 1's. The balanced codes is an effective alternative method. In the paper, The basic principle of coding is described on 8:12 balanced modulation codes. The minimum hamming distance is four between codewords. The codes can provide a single error-correction capability. It has more code efficiency than differential codes. The circuit design of encoding and decoding isn't complexity. So,the method introduced in the paper has more practicability.
