Abstract
Data storage system circuitry comprises randomizer circuitry and grading circuitry. The randomizer circuitry concurrently generates multiple randomized versions of user data. The grading circuitry selects one of the multiple randomized versions of the user data for data storage. Decoding circuitry decodes the selected one of the multiple randomized versions of the user data. In some examples of the invention, the grading circuitry selects the one of the multiple randomized versions of the user data based on zero run characteristics of the multiple randomized versions of the user data. In some examples of the invention, the user data is not encoded with a run length limit algorithm.
