ERROR PROTECTION OF DATA STORED USING VARIABLE-LENGTH HEADERS

摘要

In one embodiment, a system includes a controller and logic integrated with and/or executable by the controller. The logic is configured to cause data to be written to a first write section of a magnetic medium as a plurality of first codeword sets, and cause at least some of the data to be written to a rewrite section of the magnetic medium as one or more rewritten codeword sets. A length of at least one rewritten row stored to the rewrite section of the magnetic medium is greater than either a length of another rewritten row in the same rewritten codeword set and/or a length of at least one row in a codeword set stored to the first write section of the magnetic medium.

1. A system, comprising:
a controller and logic integrated with and/or executable by the controller, the logic being configured to:
cause data to be written to a first write section of a magnetic medium as a plurality of first codeword sets; andcause at least some of the data to be written to a rewrite section of the magnetic medium as one or more rewritten codeword sets,wherein a length of at least one rewritten row stored to the rewrite section of the magnetic medium is greater than either: a length of another rewritten row in the same rewritten codeword set, a length of at least one row in a codeword set stored to the first write section of the magnetic medium, or a length of another rewritten row in the same rewritten codeword set and a length of at least one row in a codeword set stored to the first write section of the magnetic medium.
