Abstract
In one general embodiment, a method includes narrowing down a number of data sets to be searched in an HRTD (High Resolution Tape Directory) area for a target record based at least in part on a ratio of: a number of records from a beginning of the HRTD area to the target record, and a total number of records in the HRTD area having the target record. A physical position range in the HRTD area where the narrowed number of data sets physically exist is calculated based on a linear density of a tape drive specification. A magnetic tape having the HRTD area is repositioned to a starting data set in the calculated physical position range. The narrowed range of data sets is read starting at the starting data set.
