The OCR programs I have used require 300 dpi, and I suspect that might be something that should be considered for the future as it may be that not only typed but hand written notes could be loaded right into the database in a compact fashion and the scanned images archived for backup purposes only.

That's a factor of four smaller file size, but even at 300, your figures yield about 25,000 charts per terabyte. That's four 250 gig hard drives at about $50 each (on sale).
