Abstract
In one embodiment, a system includes a controller and logic integrated with and/or executable by the controller, the logic being configured to write a data set to a first write section of a magnetic medium, the data set including a plurality of sub data sets, each including a data array organized in rows and columns, each row of the data array including a CWI-4. A first portion of the data set is stored as CWI-4 sets to the first write section of the magnetic medium with first headers. The logic is also configured to rewrite at least some of the data set as rewritten CWI-4 sets to a rewrite section of the magnetic medium as rewritten CWI-4s having corresponding rewrite headers. A length of any one of the rewrite headers is greater than a length of any one of the first headers.
