A write head 108 comprises a yoke 110 having at least a first and a second gap 112, 114 and a coil 116 for producing a magnetic field at each gap. The coil comprises a plurality of windings 118, 120 which are arranged to produce the same magnetic field strength at each gap and/or along each gap by use of a proximity effect between the windings and a respective gap. Gaps may be arranged symmetrically about a first line 214 and the windings 209, 209, 213, 213 can be arranged in a pattern symmetrically about a second line 212 where the first and second lines are offset from each other. The distance between neighboring winding portions may vary and the windings may be non-parallel to each other. The write head can be used for writing servo patterns on magnetic tape. |
