In Big Data era, the demand for large-capacity data storage equipment has been increasing continuously. Holographic data storage (HDS) has the potential of achieving storage density and data rate beyond the limits of conventional optical and magnetic technologies. Collinear HDS system is very promising and differs from conventional 2-axis HDS, because of there are not only large storage capacities and high transfer rates, but also the unique configuration. Collinear holography can produce a small, practical HDS system more easily than conventional 2-axis holography. In this paper, we introduced the principle of the collinear holography and its media structure of disc. Some results of experimental and theoretical studies suggest that it is a very effective method. We also discussed some methods to increase the recording density and data transfer rates of Collinear HDS using phase modulated page data format.
