Thin film head
A thin film is a layer of material ranging from fractions of a nanometer (monolayer) to several micrometers in thickness. The controlled synthesis of materials as thin films (a process referred to as deposition) is a fundamental step in many applications. A familiar example is the household mirror, which typically has a thin metal coating on the back of a sheet of glass to form a reflective interface. The process of silvering was once commonly used to produce mirrors, while more rece… Thin-film heads are electronically similar to ferrite heads and used the same physics. Thin layers of magnetic (Ni–Fe), insulating, and copper coil wiring materials are built on ceramic substrates that are then physically separated into individual read/write heads integrated with their air bearing significantly reducing the … See more A disk read-and-write head is the small part of a disk drive which moves above the disk platter and transforms the platter's magnetic field into electrical current (reads the disk) or, vice versa, transforms electrical current … See more Inductive heads use the same element for both reading and writing. Traditional head The heads … See more • Head crash See more The next head improvement in head design was to separate the writing element from the reading element allowing the optimization of a thin-film element for writing and a separate head element for reading.
