Claim One:
1. A method for data error recovery in a tape storage system, by a processor device, comprising: in a tape storage system using an iterative hardware and microcode decoder, initializing at least one iterative decode cycle on the buffered dataset when an uncorrectable read error occurs; for a next iterative decode cycle, building upon data corrections obtained in a previous iterative decode cycle; and initializing a microcode cut/paste algorithm on a buffered dataset; wherein a most corrected dataset recovered by the at least one iterative decode cycle is cut and pasted over a dataset resident in a reserved buffer segment, thereby improving a dataset error rate of the buffered dataset while mitigating backhitch and repositioning of a tape media from which the buffered dataset was read to reduce media and read head wear within the tape storage system.
