Sorry I can't understand it. Question was: if the system/the user ( I know nothig about the management of the bibliographic data ) knows wich image is the required one, how mutch time is accpetable for your users to wait for this data ( 1-2 seconds or 1 minute or 2 hours or 1 day are ok too? ) > > > 3.

( 1 patient 1 Disk is possible or not ) > I would suggest a standalone ( not in the jukebox integrated one ) Pioneer DVD writer with DVD jukebox method just like "Kourosh <[EMAIL PROTECTED]>" did. But there are some questions to clarify befor a real suggestion of it. Your 4TB is not to mutch. lesst then 100 DVDs 4.7 GB each. The biggest problem is the management of the robots of a jukebox library and the auto-mount/dismount of the readers. Sorry for the ad but: I'am partly owning INCOM Hungary, you can visit on the web www.incom.hu or www.incom.de. You can find HW/SW solutions for your problem. Here in Hungary we are managing/supporting a read-only system with 3300 CDs and 600 DVDs. The lifetime of the disks I think is at least 30 years. How about the HDDs or tapes?! I would make a backup copy of the disks and store it in a different building/city. You can have DVD-Rs with inkjet printable surface and you can buy printers to print the disks from 400 EUR.
