What is a DVD ?
5. DVD properties:
• Present generation of optical disc storage
• Encompass home entertainment, computers and business
information.
• Replacing CD’s, videotape, laserdisc, CD ROM and
video Game Cartridges.
• 4.7 GB of storage (up to 17 GB is possible)

6. Physical Formats of DVD-ROMs
• DVD-5 (single-sided/single-layer DVD with 4.7 GB storage)
• DVD-9 (single-sided but dual-layer disk with 8.5 GB storage)
• DVD-10(double-sided/dual-layer,9.4 GB)

7. DVD Applications
• DVD-R
• Write-once type DVD-recordable discs invented by
pioneer in 1998. this technology is used for master-disks
recording.
• DVD-ROM
• DVD Read Only Memory is a version of DVD for
computers, designed to replace the CD-ROM.it has the
same capacity as DVD-Video that is far greater than
normal CD-ROMs.

8. DVD Applications(cont.)
• DVD-RAM
DVD-Random Access Memory. Rewriteable type DVD
disc with more than 2.6 GB or 4.7 GB (DVD-RAM
Version 2) storage capacity per side supported by
Panasonic, hitachi and Toshiba.

9. DVD Data Storage
• Like CD’s data is stored in microscopic grooves running
around the disc.
• All DVD’s use laser beams to scan these grooves:
– Minuscule reflective bumps (Lands)
– Non reflective holes (Pits)

15. CONCLUSION
DVD Technology has led to advances producing a DVD
capable of holding 15 times as much data as current DVDs.
This high memory density is achieved by adding an additional
film to the DVD, pinpointing the laser beam allowing up to 30
hours of moving images to be stored, using conventional DVD
devices for playback
