The Bloch line memory is intended as a post-bubble memory hopefully to realize Gigabit density. However, there remain many uncertainties for this new technology. This paper presents the recent activities in our laboratory such as the stripe domain collapse observation using a high speed photography technique to demonstrate the wall-wall interaction, the stripe domain chopping experiment to convert the presence of a Bloch line to the presence of a bubble, and computer simulation of these phenomina and the propagation of Bloch lines in, a stripe domain wall. The importance of potential wells for Bloch line and domain wall is emphasized for successful bit by bit propagation.
