Abstract
The present invention, in particular embodiments, is directed to methods, apparatuses and systems that facilitate recording of servo signals on a recording medium such as magnetic tape with high accuracy. Variation of inter-frame and intra-frame placement is substantially reduced by writing successive frames or sub-frames based on a detection of a previously-written frame or sub-frame by a read element. Appropriate placement of the read element in relation to servo write elements, on a multi-gap servo write head, ensures the correct placement of subsequent frames on the recording medium.
