read-write heads

Read-write heads are tiny components inside devices like hard drives that access data stored on magnetic surfaces. They function like small antennas: the read head detects magnetic signals to retrieve data, while the write head alters the magnetic material to save new information. These heads float extremely close to the disk’s surface, allowing precise reading and writing without contact, which is crucial for data integrity and speed. Their accurate positioning and operation are essential for the performance of storage devices, making them fundamental to modern data storage technology.
