<p>An apparatus for texturing the front and back surfaces of a rigid-disk substrate (30) used in magnetic recording systems is disclosed. The apparatus comprises first and second mechanical assemblies; each of the assemblies including an abrasive tape (16), a load-bearing roller member (20), and a means (11, 17) for moving said tape over said roller member. Each assembly further includes a means (41, 23, 42, 21) for applying various components of force to the roller members to abrasively press the tape against the substrate surface. The invented apparatus also includes a network (55, 56, 60-63, 47, 51, 52) for mechanically coupling each of the assemblies together such that the applied force components are identical for both the front and back surfaces of the substrate. The applied forces are made independent of the substrate's position or displacement.</p> |
