OPTICAL DEVICE FOR TEXTURING DISK SURFACE WITH LASER BEAM

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 op...

Zusammenfassung:	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.
