Title: HIGH STABILITY SPIN STAND PLATFORM
Abstract:
Spin stand platform. The platform includes an air bearing puck forming a micropositioning stage. The puck is constrained for two dimensional motion on a surface. The micropositioning stage supports a read head element under test. At least one actuator moves the puck to a desired location on the surface and apparatus is provided for removing air from the air bearing puck to lock down the puck to the surface at the desired location. It is preferred that the air bearings be vacuum preloaded and that linear motors be used to move the puck.
