1. A tape head, comprising:
one or more head assemblies, each of the one or more head assemblies comprising:
a substrate;
a plurality of write heads aligned in a first row on the substrate, the first row extending in a first direction, wherein the plurality of write heads are controllable to write data to a tape;
a plurality of read heads aligned in a second row parallel to the first row on the substrate, the second row extending in the first direction, wherein the plurality of read heads are controllable to read data from the tape;
at least one writer servo head disposed adjacent to the plurality of write heads on the substrate, the at least one writer servo head being aligned with the first row in the first direction, wherein the at least one writer servo is controllable to read servo data from the tape; and
at least one reader servo head disposed adjacent to the plurality of read heads on the substrate, the at least one reader servo head being aligned with the second row in the first direction, wherein the at least one reader servo is controllable to read servo data from the tape.
