The first lens module or the at least one of the second lens modules, the light passes through the P polarized light and S-polarized light of the first polarization beam splitter for reflecting (PBS: Polarizing Beam Splitter); Relay lens collecting the light that has passed through the first polarization beam splitter; Back to the mirrors to the incident through the relay lens and the relay lens by reflecting the collected light; Alone and comprising a quarter-wave plate (Quarter wave plate), which is located between the second polarizing beam splitter and the relay lens, it converts the linearly polarized light to circularly polarized light that passes through and converted to a circularly polarized light into linearly polarized graphic data storage system can be reduced by reducing the size of the volume of the relay lens, the graphic data storage system alone, and can reduce the manufacturing cost by reducing the number of lenses.
