Fluorescent Multi-Layer Disc

  1. 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. 2. <ul><li>WHAT IS FMD? </li></ul><ul><li>Fluorescent Multilayer disc is a new technology developed by Constellation 3D Inc. </li></ul><ul><li>It stores digital data in three dimensions. </li></ul><ul><li>It is a readable and re-writable disc. </li></ul><ul><li>It is an optical data storage disc, simialar in size CD-ROMs And DVDs. </li></ul>
  3. 3. NEED OF FMD? <ul><li>Increased disc Capacity </li></ul><ul><li>Quick parallel access and retrieval information. </li></ul><ul><li>Media tolerances. </li></ul><ul><li>Usage Flexibility . </li></ul>
  4. 4. OPERATING PRINCIPLE <ul><li>The FMDs are works on the phenomenon of PHOTOCHROMISM . </li></ul><ul><li>The selection of fluorescent material. </li></ul><ul><li>Obtain fluorescent properties. </li></ul><ul><li>Simulation and Emission. </li></ul><ul><li>Filteration and Finish. </li></ul>
  5. 5. Model of FMDs
  6. 6. TECHNOLOGICAL PROCESS OF MANUFACTURE <ul><li>HOT STAMPING:- </li></ul><ul><li>Pressing of sheets. </li></ul><ul><li>Formation of layer. </li></ul><ul><li>Filling the pits. </li></ul><ul><li>Pressing of informational layers. </li></ul>
  7. 7. <ul><li>Technology Used:- WORM(Write Once Read Many) </li></ul><ul><li>Two Rules to be followed while recording. </li></ul><ul><li>The write laser should able to turn the fluorescense on or off </li></ul><ul><li>Threshold power of laser for recording and less power for reading </li></ul>FMD RECORDING
  8. 8. FMD READ DEVICE <ul><li>Reading process is carried out with the help of a photosensitive element. </li></ul><ul><li>Device can read low-power fluorescense of 10 MHz. </li></ul><ul><li>Reading speed upto 1GB/sec. </li></ul><ul><li>Mechanical speed of the derive is 450 times lower than that of DVD. </li></ul>
  9. 9. CD-ROM Vs FMD
  10. 10. COMPRASION OF DISC LAYERS
  11. 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. 12. APPLICATIONS <ul><li>Data warehouses. </li></ul><ul><li>E-commerce related data mining. </li></ul><ul><li>Storage of very high detailed archive of maps. </li></ul><ul><li>PVR (Priya Village Roadshow), HDTV. </li></ul><ul><li>Ability to store a large amount of data in uncompressed format. </li></ul>
  13. 13. ADVANTAGES <ul><li>Prevents problem of interference since it uses an </li></ul><ul><li>incoherent fluorescent light. </li></ul><ul><li>Compatible with CD and DVD formats with more </li></ul><ul><li>storage area and faster access. </li></ul><ul><li>Fluorescent technology do not require special </li></ul><ul><li>manufacturing conditions. </li></ul><ul><li>Cost of production of FMD is relatively cheap. </li></ul><ul><li>It consists multiple data layers, Capacity of each data layer is 4.7 GB </li></ul>
  14. 14. REFERENCES <ul><li>www.en.wikipedia.org/wiki. </li></ul><ul><li>www.seminartopic.org. </li></ul><ul><li>www.edu.five.org </li></ul>
  15. 15. CONCLUSION <ul><li>Man’s need for additional storage space is increasing . </li></ul><ul><li>The FMD Digital Cinema disc has the potential to provide a secure, removable, single disc distribution method. </li></ul><ul><li>The FMD can provide us with a staggering 140 GB of storage space seems to be an enticing solution for the storage- hungry masses. </li></ul>
  16. 16. Thank You
