Repositioning using cut and paste segments

Abstract:

Repositioning to a beginning of an area of a tape medium to which a reposition request is directed can be completed. Reading, as a part of an error recovery procedure (ERP), between a first dataset of the area and an m.sup.th dataset of the area, can be completed, where m is a number of datasets for which cut and paste multi segments are to be generated. Cut and paste segments for each of the datasets in a range from the first dataset and the m.sup.th dataset can be generated. A subset of datasets within the range of the first dataset to the m.sup.th dataset having readable dataset information table (DSIT) information can be determined. A determination can be made whether the target data position is included within the subset of datasets within the range of the first dataset to the m.sup.th dataset by reading the DSIT information.
