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，的长度放置了数十个读写头。

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.

该机器有一个读写头， 可每次读取一位数字，然后可少数几项任务之一。

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器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。
