Multilevel Subwavelength Optical Data Storage Using Reflective Nanostructures (NG-DVD & AO-DVD) Fred Thomas Iomega Corporation
Subwavelength Optical Data Storage In 2003 this was a $25 billion market.
A Little Background What is Subwavelength Optical Data Storage? Amazing! HEBS Glass Gray Scale Fabrication ( 2001 ) HEBS fabrication of 3 micron AO-DVD mirrors ( 2002 ). Macro scale demo of multilevel spatial encoding ( 2002 ). Original subwave storage patent filed ( 2002 ). FDTD Modeling of Subwavelength quadrature AO-DVD elements @ Uni. of Az. ( 2003 ). Papers 2002 & 2003 Subwavelength ODS Replicated nano-structures smaller than a focused light spot that upon reflection alter the basic properties of the light in a controlled manner. NanoOpto, Inc. brings nano-grating (100 nm) products to market. With Iomega explore phase, amplitude multilevel ODS ( 2004 & 2005 ). NG-DVD
Multilevel Mechanisms for Subwavelength Optical Data Storage Amplitude Domain Phase Spatial Domain Reflectivity Polarization Multiplexed Spatial
NG-DVD Media Concepts Two (2) Multilevel DVD Scale NG-DVD Data Cells Nano Birefringent Phase Retarder Nano Wire-Grid Polarizer Nano-Grating Technology Status 100 nm period parts. Tolerances < 10 nm. 50 nm period (6 months). Scales with laser wavelength.
Some Embodiments of Subwavelength Optical Data Storage AO-DVD (Articulated Optical DVD ) Articulated NG-DVD (Hybrid) Nano reflective facets that encode multi-level data spatially via multi-path reflections. 400 GB 1.2 TB Nano reflective gratings that encode muti-level data via reflective amplitude, polarization, or phase retardance. NG-DVD (Nano-Grating DVD) 200 GB 600 GB Nano reflective blazed gratings that encode muti-level data via all AO & NG DVD mechanisms. 500 GB 2.0 TB
Some NG-DVD Test Data Static Data State Tester NA = 0.65 Spot on NG-DVD Slightly Past Focus.
Some More NG-DVD Test Data Simple Spin Stand Test NA = 0.25 RPM =10,500 NA = 0.65 RPM =11,200 25 KHz DOF Vibration NA = 0.25 RPM = 10,500 Media Noise Static measurements taken for 45 属 NG-DVD orientation over 3 x 3 mm area showed noise comparable to FS mirror. ~ 1% ( laser drift noise)
AO-DVD & NG-DVD Manufacture Why this is Exciting! NanoOptos Nano Replication Process NanoOpto parts shipping: Cell phone camera IR filters DVD & CD 村 waveplates Various Telecom components. NG-DVD Cross-section Nano-Grating 90 nm period 1. Mold 2. Prepared substrate 3. Impression & Separation 4. Reactive Ion Etching 5. Post-processing: Coating and dicing Reflective layer Core Nano-structured Grating with fill. ARC - top Overcoat Substrate
Uniformity of NG-DVD Disc Results & Process Capability (4 Wafer) < 賊 2.5% Phase variation over part.
Subwavelength ODS Value Proposition within the Data Storage Landscape > 70% of all DVDs shipped are ROM. The future of optical data storage is all about shipping HDTV resolution movies at low cost. ( Technology targets driving force in market. ) NG-DVD/AO-DVD are single layer, mastered and replicated technologies. Future standard optical technologies are multi-layer. ( Cheaper to mass replicate than what is on the drawing board. ) NG-DVD/AO-DVD is a concept that can be made hybrid with standard DVD, HD-DVD & Blu-Ray technologies. Hence it has a recordable mode. NG-DVD/AO-DVD technologies development is leveraged by the huge concurrent investment in nanotechnology into the foreseeable future. ( Nanotech is hot & has long legs into the future! ) Applicable to UV stylus data storage.
What has Changed? What is Next? The required 3-D reflective media structures can now be fabricated to scale. NanoOpto Inc. is manufacturing to scale nano-grating structures (NG-DVD) with low-cost nano-replication. We know now that there is multilevel information content in reflections from a focused spot of light dwelling on both NG-DVD & AO-DVD subwavelength optical data elements. University of Arizona FDTD modeling shows that AO-DVD subwave structures provided multiplexed spatial information. Initial Iomega & NanoOpto validated data exists relative to multilevel encoding potential of nano-grating using amplitude and phase signals. Iomegas Intellectual Property position in this area is solid. Iomega Subwavelength ODS US patent issued April 12, 2005 (56 claims allowed). Iomega has additional Subwavelength ODS US patents filed. Iomega no longer is staffed for optical data storage R&D and optical drive production. We are looking for appropriate partners to bring this technology to market.
