| titleOfInvention |
Disk substrate for magnetic memory devices |
| abstract |
This invention is directed to the fabrication of substrates for rigid information disks for use in a magnetic storage device, the surface of the substrate comprising a smooth area and a low friction area. Conveniently, the substrate will comprise a photonucleable glass wherein the low friction area will have a controlled textured surface. |
