SELECTIVE HARD AND SOFT REWRITES - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240134565 titled 'SELECTIVE HARD AND SOFT REWRITES
Simplified Explanation
The present disclosure involves systems and methods for reducing rewrite overhead in a sequential access storage system. The method includes writing a data set to a sequential access medium using a magnetic head, classifying each of the encoded data blocks on the medium into one of at least three classes of write quality, and rewriting the encoded data blocks in a rewrite area based on the write quality class.

Original Abstract Submitted
the present disclosure includes systems and methods for reducing rewrite overhead in a sequential access storage system. the method may comprise writing a data set to a sequential access medium using a magnetic head, wherein the data set comprises a plurality of encoded data blocks, classifying each of the plurality of encoded data blocks on the sequential access medium into one of at least three classes of write quality, and rewriting the encoded data blocks in a rewrite area of the sequential access medium based at least in part on the write quality class. in some embodiments, the at least three classes of write quality may comprise a hard rewrite class for which rewrites are necessary to prevent data loss, a soft rewrite class for which rewrites are desirable but not necessary, and a no rewrite class for which no rewrite is needed or desired.
