Reminds me of Bubble Memory from the late 1980's. It used a magnetic field to push magnetic domains ("bubbles") along a track and eventually they'd get to a read/write zone. So, sequential access but things could be parallelized by having multiple read/write zones.
Flash memory came along and was better, so bubble memory was abandoned.
