Perpendicular hard drives

  S5W 19:07 30 Aug 06

I logged in tonight to ask this question but was so appalled by the story of the motorcyclist and the WPC that I forgot.
Does the perpendicularity of the bipoles refer to the disk surface or to its circumference? If the former how is it achieved? Will someone kindly satisfy my curiosity?

Thanks santoz7, I did read the article but my question is "perpendicular to what" ie do the individual magnets run through the thickness of the disk or radially on the surface?
