ABSTRACT:
A method and apparatus for precision machining a surface suitable for use as a data recorder, using a scanning probe microscope (SPM) capable of observing an electrically insulating surface. The SPM includes a probe which comprises a tip having a pointed end, and also including a conductive layer applied on a surface of the tip. The tip is brought into close proximity to the surface which is to be machined and a machining voltage is applied between the tip and the surface to machine the surface.
