It fits neatly in your wallet as well as the drawer of your PC. British
company MCB Digital Media (www.romcard.com) is making CD-ROMs that look like
business cards. Because CDs play from the centre out, the data tracks on the
鈥淩OMcard鈥� cover a circle bounded by the rectangular shape. This small area can
store 20 megabytes of data, equivalent to a dozen floppy discs and enough for
addresses, maps, publicity pictures and an Internet link. Four small protrusions
from the underside of the card centre the rectangle in the tray of your CD-ROM
drive, so that it spins like an ordinary disc.
