Fabrication and Recording of Bit Patterned Media Prepared by Rotary Stage Electron Beam Lithography

Moneck M.T., Lin W., Powell S., Okada T., Fujimori J., Kasuya T., Katsumura M., Iida T., Kuriyama K., Bain J., Zhu J.-G., Carnegie Mellon University, US

Bit patterned media (BPM) is a promising technology for magnetic recording at ultra-high areal densities beyond 1 Tbit/in2. To be viable, bit patterns must be reliably fabricated across 2.5” disks with few defects and sigma [...]

Development of Methanol Based Reactive Ion Etching Processes for Nanoscale Magnetic Devices

Moneck M.T., Zhu J.-G., Carnegie Mellon University, US

Recent advances in the area of magnetoelectronics include the development of bit patterned media (BPM) for hard disk drives and the realization of spin transfer torque (STT) devices. As feature sizes shrink to sub-50 nm [...]
