Roadmap for 10 Gbit/in2 media: challenges

The authors examine the requirements for 10 Gb/in² media, taking guidance from a recording model and known trends in high-performance media. They apply a read/write model to examining the media properties required for this density in a practical drive application. They find that the required magnetic and microstructural properties with the concomitant noise and supermagnetic limits demand significant improvements over existing media, to the extent that revolutionary improvements will likely be required
