Abstract:
Laser texturing apparatus includes an acousto-optical modulator which deflects a continuous laser beam into a first optical projection path to texture a first side of a disk or into a second optical projection path to texture a second side of the disk. The modulator causes lateral movement of the laser beam in a first direction as it is initially deflected into the first optical projection path and at the end of its deflection into this path. The modulator also caused lateral movement of the laser beam in a second direction as it is initially deflected into the second optical path and at the end of its deflection into this path. Each optical projection path is configured so that this lateral movement is in the direction of movement of the disk being textured at the spots at which it is textured.
