Adaptive-rate error correction layer for tape storage

A system, comprising:

• a processor;
• and
• a memory coupled with the processor, wherein the memory is configured to provide the processor with instructions which when executed cause the processor to:
• determine data set groups, wherein each data set group includes a plurality of data sets and each data set includes error-correcting information for content user data of the data set;
• calculate one or more versions of data set group level error-correcting information for each data set group of the data set groups;
• provide an instruction to store the data set groups on a tape storage media;
• after the data set groups are stored on the tape storage media, identify an amount of storage available on one or more regions of the tape storage media associated with one or more tape edges;
• and
• provide an instruction to store at least a partial amount of the calculated one or more versions of data set group level error-correcting information for the data set groups able to be stored in the amount of storage available on the one or more regions of the tape storage media associated with the one or more tape edges.

A computer program product, the computer program product being embodied in a tangible computer readable storage medium and comprising computer instructions for:

• determining data set groups, wherein each data set group includes a plurality of data sets and each data set includes error-correcting information for content user data of the data set;
• calculating one or more versions of data set group level error-correcting information for each data set group of the data set groups;
• providing an instruction to store the data set groups on a tape storage media;
• after the data set groups are stored on the tape storage media, identifying an amount of storage available on one or more regions of the tape storage media associated with one or more tape edges;
• and
• providing an instruction to store at least a partial amount of the calculated one or more versions of data set group level error-correcting information for the data set groups able to be stored in the amount of storage available on the one or more regions of the tape storage media associated with the one or more tape edges.
