摘要： A disk texturing tool is used, for example, to provide textured spots in an annular portion of both sides of a hardfile disk. An optical system includes a laser directed at a beamsplitter to split the laser beam into two beams having approximately equal power, which are directed along parallel paths through a power control optics block to expose simultaneously opposite sides of a disk to be textured. A visible laser beam is also directed along this optical system to an inspection spot on each side of the disk, by which a central portion of each textured spots passes. A beam angle detector detects deflection of a reflection of the inspection beam from this spot in the direction of motion of the disk at this spot. This deflection provides a measure of the topography of the spot.
