recording head

A recording head is a component in devices like tape recorders, hard drives, or other magnetic storage systems that writes data onto a magnetic surface. It typically consists of a coil of wire and a small magnetic core. When electrical signals pass through the coil, it creates a magnetic field that magnetizes tiny areas of the storage medium, encoding information. Essentially, the recording head acts as the "writer" that imprints data onto the medium using magnetic fields, enabling the storage and later retrieval of digital information.
