Magnetic recording heads

Magnetic recording heads are small devices used in devices like hard drives and tape recorders to write and read data. They work by creating tiny magnetic fields that change the magnetization of a medium, such as a disk surface or tape. When recording, the head alters the magnetic particles to represent data; when reading, it detects the magnetic signals to retrieve information. These heads need to be very precise and close to the medium to accurately read and write data, enabling the storage of digital information you access on computers and other electronic devices.
