How does it Work? How are data recorded? Bits are encoded into an array (page) of > 1 million pixels and recorded into the media via a laser.
Recording Data Storage Medium Refere

Spatial Light Modulator
How is capacity achieved? Hundreds of pages are recorded at the same location in the media, each with its own angular address.
How are transfer rates achieved?
Recorded data
Data Pages Laser
Reading Data Detector Refere

The entire array (page) is exposed for ~ 2 milliseconds. The media does NOT move while data are being recorded or recovered. Laser

InPhase Zerowave™ Media Manufacturing Process Excellent optical quality & thick media 100 Å
3” x 3”, 1 mm-thick media Proprietary DVD-like media fabrication method allows for Routine fabrication of media with better than λ/4 / cm2 flatness enables high fidelity data storage and recovery May 2008
19
Tapestry™ Recording Material Proprietary Two Chemistry Approach BLUE, GREEN, RED, Re-Writable Resin consists of matrix precursors and imaging components
Media is fabricated from independently polymerizable and compatible matrix and imaging components
3 In-situ matrix formation: thick, optically flat formats with good mechanical robustness In-situ formation of cross-linked matrix
3Cross-linked matrix: stable holographic gratings long archival life 3 Compatible matrix and monomer systems: optical clarity and low levels of light scatter
Writing chemistry is independent of host formation chemistry
May 2008
3 Independent matrix and monomer systems: no cross-reactions- maximizes refractive index contrast.
