This little-known city in the Pearl River delta makes 30% of the magnetic recording heads used in hard drives across the world and 16% of the world's electronic keyboards.
A single town half-way between Shenzhen and Guangzhou, in an area which used to be all collective farms, started off making toys in township and village enterprises and by 2002 was producing 40% of the magnetic recording heads used in hard-disk drives throughout the world.Something similar is happening in India, albeit in a more confusing manner.
Nanometrics makes equipment to monitor the production process used in the fabrication of chips, magnetic recording heads used in disk drives and flat panel displays.
These include magnetic recording media for audio and video digital recording, as well as recording heads used with magnetic disks.
Prior to MEG recordings, the location and orientation of the MEG coils relative to each subject's head were determined by digitizing a set of fiducial reference points on the head using a magnetic digitizer (Polhemus 3SPACE).

Next, scientists here at Newcastle University's Institute of Neuroscience induce small electric currents in different parts of my head, using a technique called transcranial magnetic stimulation (TMS).
Although I.B.M. was a pioneer in the business of disk drives -- a data-storage medium that uses magnetic heads to read spinning disks -- the company fell behind its faster-moving competitors.
The Headsight, built by Philco, in 1961, used magnetic head tracking and separate video projections for each eye.
Recently, magnetic thin films used in magnetic components, such as inductive devices and magnetic heads,have attracted more and more attention because of the increasing demand for improvement and miniaturization of electromagnetic devices [1 3].
