Claim 17:
18. A tape drive, comprising:
a first head assembly, comprising:
a first substrate;
a plurality of first write heads aligned in a first row on the first substrate, the first row extending in a first direction, wherein the plurality of first write heads are controllable to write data to a tape;
a plurality of first read heads aligned in a second row parallel to the first row on the first substrate, the second row extending in the first direction, wherein the plurality of second read heads are controllable to read data from the tape;
at least one first writer servo head disposed adjacent to the plurality of first write heads on the first substrate, the at least one first writer servo head being aligned with the first row in the first direction, and wherein the at least one writer reader servo is controllable to read servo data from the tape; and
at least one first reader servo head disposed adjacent to the plurality of first read heads on the first substrate, the at least one first reader servo head being aligned with the second row in the first direction and aligned with the at least one first writer servo in a second direction perpendicular to the first direction, wherein the at least one first writer servo head and the at least one first reader servo head are configured to operate concurrently, and wherein the at least one first reader servo is controllable to read servo data from the tape;

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

a controller configured to operate the at least one second writer servo head and the at least one second reader servo head concurrently.
