ABSTRACT:
A method for fabricating a holeless hologon disk includes the steps of relatively positioning a disk assembly and a drive shaft assembly in closely spaced relation with the planar surface of the disk normal to the drive shaft's rotational axis. Adhesive is applied between the assemblies and allowed to fix while the relative assembly positions are maintained. In one construction fabricated by such method, the disk assembly comprises a flanged coupling attached to a planar glass disk with compliant adhesive.
