Hitachi Maxell Develops Wafer-Thin Storage Disc
narramissic writes "Hitachi Maxell Ltd. has developed an optical disc that is less than 1/10 of a millimeter thick. Working prototypes on display at this week's Ceatec Japan 2006 exhibition are based on DVD technology and are capable of holding 4.7 GB each. Making discs so thin doesn't come without its problems, however. To make the discs rigid enough for the laser to remain in focus on the disc's surface, the company has fitted inside each drive a 0.6 millimeter-thick piece of glass through which there are holes. Air is drawn through the holes when the disc spins causing the flexible disc to be drawn against the rigid piece of glass to make it flat."
So it seems that these aren't meant to be something that you'd carry around loose the way you do with CDs/DVDs. They'd be encased in cartridges, and those cartridges would be in some sort of device. So I think the question would be, how would this technology compare with hard drives?
