Materials Challenges for Future Magnetic Recording Media

Materials Science Special Colloquium
Bruce D. Terris, HGST
January 9, 2014 11:00AM to 12:00PM
Building 241
The Colloquium takes place at the Energy Sciences Building 241, Rm. D-172.

The rate of creation and generation of data continues to explode, and the dominate technology used to store data continues to be magnetic hard drives. However, the rate of areal density growth in hard drives is decreasing and the often predicted but yet to be reached limit may be nearing. In this talk, I will briefly discuss why hard drives will continue to be the pervasive data storage technology, and what some of the materials science challenges are to continue the density growth.

In a particular, what advances are needed to continue density growth of today’s CoPtCr based perpendicular technology, and how far can the media recording density be extended? What is needed to bring Heat Assisted Recording (HAMR) to the market, and why is FePt media still a significant challenge? What are the media challenges and technology prospects for Microwave Assisted Recording (MAMR) and for Bit Patterned Media (BPMR)? An overview of these new potential technologies and the magnetic media requirements will be presented.
