   Which is exactly the problem.   
      
   Your DVD 'media' might survive 1,000 years.  But if you can't buy a DVD   
   reader for any price, all that 'media' is useless.   
      
   We've already seen that issue before.  Try to find a Zip disk or   
   SuperDisk drive.  If any could be purchased, they would all be from   
   places like eBay and of questionable operational quality.   
      
   The reality is the only way to 'archive' is to periodically copy one's   
   archived data to newer storage systems, which involves at least the   
   work of the actual copy process (and which must occur before the   
   mechanical devices for the old media fail) and of verification that the   
   copy process did not itself corrupt the data.
