Now this is mostly irrelevant to what we're talking about except for the fact that there are magnetic particles involved and they're really small because it turns out what's inside most of your laptops and desktop computers are these things called hard drives.

其实这与我们现在谈论的话题没什么关系,除了这里的磁性粒子有关系外,它们是很小的因为它们要放在,你的笔记本电脑或者,台式机中被称为硬盘的里面。
