Beschreibung
Zusammenfassung:	A system and method of operating a dual-beam detection system of a holographic data storage disc, including: impinging a data beam on a data layer of the holographic data storage disc; impinging a tracking beam on a tracking element of the holographic data storage disc; detecting a reflection of the tracking beam from the tracking element; and coordinating position of the data beam relative to the tracking beam. Embodiments compensate for the variation in vertical spacing of data and tracking beams due to the data beam being uncollimated at the objetive lens
