Abstract:
An optical disk apparatus comprising:a light source for emitting a laser beam; an objective for focusing the laser beam; a slider holding the objective and arranged to float relative to an optical disk; a suspension for supporting the slider; a first mirror supported by the suspension and spaced from the slider in a focusing direction, the first mirror being arranged to reflect the laser beam traveling in a first direction which is non-parallel to the focusing direction, so that the reflected laser beam enters the objective; and a seek mechanism for moving the suspension so that the first mirror and the slider are moved in a tracking direction; wherein the first mirror is rotatable about a first axis for causing the reflected laser beam to shift in the first direction; and wherein the first mirror is rotatable about a second axis which is non-parallel to the first axis for causing the reflected laser beam to shift in a second direction which is non-parallel to the first direction.
