Question: 1 / 400

The disk in the disk drive rotates at high speed, and the heads in the disk drive are used only to read data. Is this statement true?

True

False

The statement is false because, in addition to reading data, the heads in a disk drive are also responsible for writing data to the disk. The operation of a disk drive involves both reading and writing processes. When data is saved, the read/write heads change the magnetic properties of the disk surface to encode the new information. Conversely, when data is retrieved, those same heads read the magnetic charges and convert them back into a digital format for processing. Therefore, the dual functionality of the heads in disk drives is essential for their operation, reinforcing that they not only read but also write data.
