A novel high speed, high capacity electron-beam  recording technique using nano technology in a Hard  Disk Drive form factor is described. The e- beam source  is a carbon nanotube (CNT) emitter and can be gated at  rates up to several gigahertz. The planned recording  media is Phase Change with sub-nanosecond response  times, and data read-out by Secondary Electron  Emission is anticipated. The key parameters for  generating the recording beam are described and a  preliminary design is discussed in which the CNT based  ReadiWrite head replaces the magnetic head in a  standard Hard Disk Drive (HDD). The technique  sidesteps limits associated with HDD technology and  potentially provides far higher recording densities and  higher data rates than possible with conventional  magnetic-recording. The NS3 NanoTech Disk (NTD)  approach may provide a path forward for HDD's to the  low nanometer mark scale.
