    摘要： A system for use with a data storage media having at least one groove proximate a surface thereof and a plurality of volumes therein, including: objective lensing; a first tracking error detector optically coupled to the objective lensing and being responsive to reflections from the at least one groove; a first actuator coupled and responsive to the first tracking error detector; a second tracking error detector optically coupled to the objective lensing and responsive to reflections from micro-holograms contained in at least some of the volumes; and, a second actuator coupled and responsive to the second tracking error detector; wherein the first and second actuators cooperate to selectively position the objective lensing to focus a light beam into a target one of the volumes.

    摘要： A method for encoding in a holographic disk storage medium is provided. The method includes recording multiple micro-holograms such that the micro-holograms are aligned across a respective plurality of tracks and across a respective plurality of layers at a pre-determined location of an original holographic disk. The method also includes detecting a characteristic waveform signal of a reflected beam from the original holographic disk. The method further includes detecting a second waveform signal from a second holographic disk. The method also includes comparing the second waveform signal with the characteristic waveform signal. The method further includes determining authenticity of the second holographic disk based upon comparison.
