A volume holographic data storage (VHDS) system incorporates therein a storage device having a plurality of storage media for storing multiple holograms. The VHDS system comprises a light source for generating a coherent light beam, a beam splitter for splitting the coherent light beam into a reference and a signal beams, a storage device having a base and a plurality of storage media mounted on the base for three-dimensionally storing the multiple holograms thereinto, a pair of mirrors for directing the signal and the reference beams to the storage device, respectively, and a motor for rotating the storage device about an axis perpendicular to a plane which includes the signal and reference beams, wherein the axis passes through a center point of the storage device. In the storage device, each of the storage media is mounted on top of the base angularly separated by an angle of betadegrees.
