ABSTRACT:
A system to write a servo signal pattern onto a recording medium incorporating a transducer with a full-width write head, and one or more slotted erase head(s). The full-width write head is used to record signals across the full width of the recording medium; the erase head(s) is used to erase "nulls" in the servo signal pattern. The resulting servo pattern has an extremely good match of signal characteristics between the different portions of the resulting signal pattern, since the recorded patterns were all written in the same pass by the same write head. The use of precisely fabricated and aligned erase head(s) results in a very accurate signal pattern.
