  1. CD Versus DVD technology ? And Beyond ?

  2. CD versus DVD versus ?Current, Future, and Beyond • The information on a CD can be straightened into a line that is over 3 miles long. • The information on a DVD can be straightened into a line that is over 7.5 miles long. • The information on a HD-DVD & Blu-Ray can be straightened into a line that is over 75 miles long.

  3. The Current:Toshiba vs Sony • Toshiba Format = HD-DVD • Sony Format = Blu-Ray The Near Future:Ricoh • Ricoh Format = Any Format

  4. Holographic Memory Future Future ? ? 50 Movies storied on 1 cubic centimeter of media! In a holographic memory device, a laser beam is split in two, and the two resulting beams interact in a crystal medium to store a holographic recreation of a page of data. The amount of information will greatly increase for the laser doubling. For what there is to come. Will they continue to split the laser beams or will there be a completely different approach.
