Abstract
Drive technologies predicted to be necessary to achieve the areal density of 200 Gb/in/sup 2/ is presented. A two-stage actuator is described that effectively reduces non-repeatable runout to less than 12 nanometers, making it possible to increase track density. A concept of smaller-sized high speed HDD is also proposed, and that application is enlarged to web-server or consumer product.
