Methinks you'd wear the > drives (both readers and burners) out very quickly, too. JVC makes a 600 disk changer. You'd only need 3 of them :) I have no idea how expensive they would be though. It could be that a half a dozen such changers would be more effective than any muddling with disks. Once the media is burned it shelf life is fairly long and in an emergency you can manually load from any desktop peecee. Granted, making sure you filled dieks to capacity and had correct indexes would be the difficult part but it is an option, and probably cheaper than DLT when you consider media costs. -- | Matthew N.
