Transcript

  • 1. A Presentation On Fluorescent Multi-Layer Disc Guided By Presented By Mr. Prahlad Kumawat Rahul Kumar Mahaych SRI BALAJI COLLEGE OF ENGG. & TECH.
  • 2.
    • WHAT IS FMD?
    • Fluorescent Multilayer disc is a new technology developed by Constellation 3D Inc.
    • It stores digital data in three dimensions.
    • It is a readable and re-writable disc.
    • It is an optical data storage disc, simialar in size CD-ROMs And DVDs.
  • 3. NEED OF FMD?
    • Increased disc Capacity
    • Quick parallel access and retrieval information.
    • Media tolerances.
    • Usage Flexibility .
  • 4. OPERATING PRINCIPLE
    • The FMDs are works on the phenomenon of PHOTOCHROMISM .
    • The selection of fluorescent material.
    • Obtain fluorescent properties.
    • Simulation and Emission.
    • Filteration and Finish.
  • 5. Model of FMDs
  • 6. TECHNOLOGICAL PROCESS OF MANUFACTURE
    • HOT STAMPING:-
    • Pressing of sheets.
    • Formation of layer.
    • Filling the pits.
    • Pressing of informational layers.
  • 7.
    • Technology Used:- WORM(Write Once Read Many)
    • Two Rules to be followed while recording.
    • The write laser should able to turn the fluorescense on or off
    • Threshold power of laser for recording and less power for reading
    FMD RECORDING
  • 8. FMD READ DEVICE
    • Reading process is carried out with the help of a photosensitive element.
    • Device can read low-power fluorescense of 10 MHz.
    • Reading speed upto 1GB/sec.
    • Mechanical speed of the derive is 450 times lower than that of DVD.
  • 9. CD-ROM Vs FMD
  • 10. COMPRASION OF DISC LAYERS
  • 11. CD vs DVD vs FMD PARAMETERS CD DVD FMD 1.Disc Diameter 1.2mm 1.2mm 1.2mm 2.Capacity 750MB 4GB 50GB+ 3.Wavelength 780nm 650nm 480-530nm 4. Distance b/w Tracks 1.6micron 0.85micron 0.80micron 5.No.of layers 1 2 12
  • 12. APPLICATIONS
    • Data warehouses.
    • E-commerce related data mining.
    • Storage of very high detailed archive of maps.
    • PVR (Priya Village Roadshow), HDTV.
    • Ability to store a large amount of data in uncompressed format.
  • 13. ADVANTAGES
    • Prevents problem of interference since it uses an
    • incoherent fluorescent light.
    • Compatible with CD and DVD formats with more
    • storage area and faster access.
    • Fluorescent technology do not require special
    • manufacturing conditions.
    • Cost of production of FMD is relatively cheap.
    • It consists multiple data layers, Capacity of each data layer is 4.7 GB
  • 14. REFERENCES
    • www.en.wikipedia.org/wiki.
    • www.seminartopic.org.
    • www.edu.five.org
  • 15. CONCLUSION
    • Man’s need for additional storage space is increasing .
    • The FMD Digital Cinema disc has the potential to provide a secure, removable, single disc distribution method.
    • The FMD can provide us with a staggering 140 GB of storage space seems to be an enticing solution for the storage- hungry masses.
  • 16. Thank You
