Abstract
Disclosed are a magnetic tape capable of suppressing deterioration of the S/N ratio of the data and servo signals and adapted to high density recording design, and a servo writer capable of producing the above magnetic tape. Further, the magnetic tape includes a DC-magnetized DC written region, a servo signal being written onto the DC written region, and a data track. Here, the DC written region and the servo signal are formed to satisfy a relationship −1.5×Tw≦Fd≦1.5×Tw, where Fd denotes a position of an end of the DC written region with respect to an end of the servo signal, and Tw denotes a width of the data track.
