University archaeological education, CD-ROMs and digital media

Abstract

I would like to start with the contentious assertion that there is very little special about CD-ROMs; they are little more than overgrown floppy disks with a long shelf-life, and uncertain sell-by date. A CD-ROM can contain about 650 Mb (Megabytes) of digital information, the equivalent of 450 high-density floppy disks, A CD-ROM is much more durable than a floppy disk, if kept away from small children and dogs, and is certainly more convenient to transport and handle than 450 floppy disks. A floppy disk will fade and its contents will become unreadable after about 4 or 5 years. A shiny CDROM on the other hand will last physically for at least 30 years, we are promised. Unfortunately the CD-ROM is already headed for the scrap heap of our technological past and is set to join the burins and scrapers. Yes, the Digital Versatile Disk (DVD) is coming our way. It can contain up to 17 Gb (Gigabytes) — that’s 17 with nine zeros after it, the equivalent of 11,805 floppy disks full of data. Fifteen years ago, back in 1982, a 10-Mb hard disk was considered an expensive technological marvel with more than enough capacity (equivalent to 25 of the lowercapacity, 400-Kb floppy disks of the ‘80s). Nowadays, the CD-ROM, given away on the front of glossy magazines, and costing Sop to produce, contains 65 times that amount of information. My point is that I don’t think we should become obsessed with the technology and the means of delivery of data on some kind of disk. What is far more important is what is actually on the disk — the message not the messenger.
