Let's zoom in on the read write head.

让我们放大读写头。

The drum was rotated continuously, and positioned along its length were dozens of read and write heads.

鼓不断旋转，沿着它的长度放置了数十读写头。

The machine has a read-write head that can read one digit at a time, and then it can perform one of only a few tasks.

该有读写头， 可以每次读取位数字，然后它可以执行少数几项任务之。

After that, we'll  dive into exactly how the drive stores data using the read and write head, and in the process, we'll  look at the tracks, sectors, and magnetic domains of the metal disk.

之后，我们将深入了解驱动如何使用读写头存储数据，在此过程中，我们将研究金属磁盘的磁道、扇区和磁畴。
