Tape head surface with non-uniform cross-width edge profiles

A method of operating a tape drive, comprising:

• first moving a tape over a first module of a tape head, wherein the first moving includes:
• passing a first track of the tape over a first edge portion of the first module;
• passing a second track of the tape over a second edge portion of the first module, wherein the second track of the tape is spaced from the first track of the tape along a reference line that is perpendicular to first and second opposite lateral edges of the tape, and wherein the first edge portion of the first module is sharper than the second edge portion of the first module;
• and
• passing the first track of the tape over a span of transducers of the first module;
• and
• second moving the tape over a second module of the tape head, wherein the second moving includes:
• passing the second track of the tape over a first edge portion of the second module;
• passing the second track of the tape over a span of transducers of the second module;
• and
• passing the first track of the tape over a second edge portion of the second module, wherein the first edge portion of the second module is sharper than the second edge portion of the second module.
