Tribo electrification of nano-gap giant magneto-resistive heads during high revolutions per minute glass disk rotation
Contact electrification or Tribo-electrification is a well known phenomenon when two materials of different work functions come into contact and separate. Head Disk Interfaces or HDI between sensor and disk platters has been decreasing in the past years approaching nanometer levels. HDI is also call...
