- [absolutely correct, the computer industry will move to the new blue-light
- lasers, however I'm pretty sure these new drives will be downward compatible
- with todays CD-ROM players. Kodak can decided to do the same with its
- "professional" versions of the CD. There is a new trend in the industry
- to included CD-ROM drives as standard equipment on personal computers at
- affordable prices. (eg. Apple and Sun). Personal computers prices are
- dropping incredibly fast. Besides, 15 years in computer
- years is equivalent between the difference of the Mesozoic and Cenozoic
- eras. Within 15 years we will have some sort of affordable high capacity
- writable medium for which we can make our own transfers. Fifteen years
- is sufficient time for the computer industry to come up with a solution.]

- Exactly my point. If the PhotoCD becomes successful there will be money
- to be made in transfering the photoCD images to a new medium. If
- you look in the back of many computer publications, there are small
- companies who specialize in data transfers between mediums. If a large
- enough market exist 10 years from now, there will be incentive for
- some entrepreneur to do the same for the PhotoCD unless Kodak themselves
- beat them to it. As for the propriety compression Kodak uses, this
- is where I see a legitimate beef. Kodak should be encouraged to
- release this information.
-
- Besides, who ever said just because you have a CD negative that you
- have to get rid of the original negative/slide? A CD negative makes
- a good companion in which you can create prints off the CD, keeping
- the original safe. And if a new technology comes around, just rescan
- the darn thing or have the digital image transfered. Use the CD for
- presentations on projection t.vs or for distributing proofs or what not.
-
- Honestly, I can understand the concern over resolution, but not this
- long term storage debate. No one ever said to burn your negatives.
