A stripe domain (SD) was stabilized by a patterned Co-Cr film. The bias field range for the stabilization was 2 or 3 Oe. The SD was stretched and shrunk for read-write operation. Vertical Bloch lines (VBLs) were observed by rocking under the Co-Cr pattern 10 µm in width. A VBL pair was propagated continuously around the SD by applying pulsed bias fields perpendicular to the film. The motion of the VBL pair was observed by rocking. The velocity of the propagation was about 2.0×10⁴ cm/s at pulse amplitude 40 Oe and pulse width 8 ns. This was comparable to that of the SD stabilized by a loop conductor: 2.5×10⁴ cm/s
