Getting from there to a real computer memory would be a long road.
但是要制成真正的计算机存储器还有很长的路要走,
For a start, the grains of magnetite are not strong enough magnets to make a useful memory, and the size of each domain is huge by modern computing standards.
首先对于可用的存储器来说,那些磁铁颗粒的磁性还不够强大,并且每个区域的尺寸对现在计算机标准来说太大了。
