Abstract: PROBLEM TO BE SOLVED: To provide a disk texture tool for giving a texture spot by irradiating annular parts on both sides of a hard file disk with a laser beam. SOLUTION: A disk is moved while being housed in a cassette and subjected to the texture process through two disk processing stations. An optical system introduces a laser beam 131 to a beam splitter 132 and the laser beam is divided into two beams. Two beams have approximately equal power, travel toward a power control optical block along a parallel paths and both surfaces of the disk to be given by the texture are irradiated with the beams through the block. The power control optical block 136 has an attenuating/measuring means of two beams, respectively. A mirror moving left and right alternately sends two beams to the two disk processing stations.

Abstract: A disk texturing tool is used, for example, to provide textured spots in an annular portion of both sides of a hardfile disk. Disks are moved into and out of the texturing process in cassettes, through two disk-handling stations. An optical system includes a laser directed at a beamsplitter to split the laser beam into two beams having approximately power, which are directed along parallel paths through a power control optics block to expose simultaneously opposite sides of a disk to be textured. The power control optics block includes means for attenuating and measuring each of the two beams. A shuttling mirror directs these two beams alternately at a disk within each of the two disk handling stations.
