An optical disc cutting apparatus capable of suppressing an unnecessary
deflection component and unnecessary light intensity variation component
and manufacturing a optical disc suitable for a high definition, high
precision and high density optical disc. The optical disc cutting
apparatus includes a light beam controller including at least one of an
optical modulator for controlling the light intensity of light beam
emitted from a laser beam source and an optical deflector for controlling
the deflection amount of the light beam in the radial direction on an
optical disc original master, a deflection error detector for detecting a
deflection error in the radial direction included in the light beams
controlled by the light beam controller, a second optical deflector,
which is disposed between the light beam controller and the deflection
error detector, for deflecting the light beams in the radial direction,
and a feedback controller for feeding back a feedback signal using the
deflection error in the radial direction to the second optical deflector.
