    摘要: In a focus optical system for optical discs or optical disc master exposure apparatuses, a relative positional relation between a cylindrical lens and a 4-division detector in an astigmatic optical system is adjust so that an interference fringe appearing in reflected light derived from an optical disc master is made to be incident on a dead zone of the 4-division detector. Thus, an astigmatic focus servo free from effects of variations in a focus error signal due to the interference fringe is realized. As a result of this, effects of the interference fringe appearing in the reflected light derived from an optical disc or optical disc master can be suppressed.

    摘要: A method for transferring a thin plate is provided, in which three or more grasping claws of a transfer arm grasp the periphery of the thin plate in order to transfer it to a predetermined transfer position, and three or more holding claws hold the periphery of the thin plate in the transfer position. The transfer arm rotates about a shaft which is in a direction of a vector sum of a first vector perpendicular to a surface of the thin plate before transfer, and a second vector perpendicular to the surface of the thin plate after the transfer, to transfer the thin plate with changing the posture thereof.
