ABSTRACT:
A tape drive writes/reads tapes written in a format which stores an increased amount of data because the tracks overlap. The wide write
arrow read heads read a center portion of each track which does not have overlap. The new format is identified by the positions of a reference burst, by encryption of the bad sector map, and by alteration of the tape signature to prevent unqualified drives and software from operating upon tapes in the new format.
