The read operation performance in Bloch line memory has been studied using a typical 2 um bubble material. A reasonable operation margin for a chopping detection of vertical Bloch line was performed with a hair-pin type chopping conductor with the 4 um pattern width and 1.5 um pattern gap. The chopping current margin and the bias field margin are 146 mA ± 4.1 %, and 107 Oe ± 6.1 %, respectively. Domain wall configurations during the chopping process have been studied numerically, comparing with experimental results.
