Coding for high-density magnetic recording

Arya Mazumdar, Alexander Barg, Navin Kashyap

Abstract: We study a model of errors in binary data that arises in terabit-density magnetic recording. Under this model, several bits of the data are replaced by the values of their neighbors on the medium. We consider a simple one-dimensional version of this model, and derive several properties of codes that correct this type of error.
