Abstract

See full text

The present disclosure is generally related to a tape drive including a tape head configured to read shingled data on a tape. The tape head comprises a first module head assembly aligned with a second module head assembly. Both the first and second module head assemblies comprises a plurality of data heads. Each data head comprises a write head, a first read head aligned with the write head, a second read head offset from the first read head in both a cross-track direction and a down-track direction, and a third read head offset from the first and/or second read heads in the cross-track and down-track directions. By utilizing three read heads within each data head, data can be read from a tape that has experienced tape dimensional stability, as at least one read head will be near a center of each data track of the tape.
