Nanotech To Replace Disk Drives Within Ten Years? 127
Ian Lamont writes "An Arizona State University researcher named Michael Kozicki claims that nanotechnology will replace disk drives in ten years. The article mentions three approaches: Nanowires (which replace electrons/capacitors), multiple memory layers on silicon (instead of a single layer), and a method that stores multiple pieces of information in the same space: 'Traditionally, each cell holds one bit of information. However, instead of storing simply a 0 or a 1, that cell could hold a 00 or a 01. Kozicki said the ability to double capacity that way — without increasing the number of cells — has already been proven. Now researchers are working to see how many pieces of data can be held by a single cell.'"

Hard disks are absolutely, with no qualification, nanotechnology. In fact, hard disks were the *first* nanotechnology we ever used, anywhere. Each bit on a modern hard disk is literally nanometers on a side, the read head is a thin film nanometers in thickness, flying above the disk less than a micron above the surface! Saying that nanotechnology will replace that is like saying that wheat will replace rye as the best sandwich containing substance. Moronic.
When I was helping with a proposal to the EPA for regulating the environmental effects of nanotech, I needed to come up with a definition for nanotechnology. The *only* definition that exists for nanotechnology is a system where the relevant controlled length-scale is less than 100nm. Hard drives are the most advanced nanotechnology on earth!

Four possible values, not four times as many values.
Apparently, I can't count.
