Abstract: Heat-assisted magnetic recording is a promising approach for enabling large increases in the storage density of hard disk drives. A laser is used to momentarily heat the recording area of the medium to reduce its coercivity below that of the applied magnetic field from the recording head. In such a system, the recording materials have a very high magnetic anisotropy, which is essential for the thermal stability of the magnetization of the extremely small grains in the medium. This technology involves new recording physics, new approaches to near field optics, a recording head that integrates optics and magnetics, new recording materials, lubricants that can withstand extremely high temperatures, and new approaches to the recording channel design. This paper surveys the challenges for this technology and the progress that has been made in addressing them.

Dynamic Fly Performance of Air Bearing Sliders on Patterned Media
J Hanchi,P Sonda,Robert M. Crone +2 more
TL;DR: One of the challenges associated with the practical implementation of patterned media technology, namely, the impact of non-planarity, and shifts in pattern orientation (at data-servo transitions, in particular) on the dynamic fly performance of air bearing sliders is concerned.

Tuning the Curie temperature of L10 ordered FePt thin films through site-specific substitution of Rh
D. B. Xu,D. B. Xu,Cheng-Jun Sun,Jingsheng Chen,Tiejun Zhou,Steve M. Heald,Anders Bergman,Biplab Sanyal,Gan Moog Chow +8 more
TL;DR: In this paper, a model of antiferromagnetic defects caused by controlled substitution of the Pt site, reducing the Curie temperature, is proposed to interpret this phenomenon and its validity is further examined by ab initio density functional calculations.

A Shingle-Aware Persistent Cache Management Scheme for DM-SMR Disks

- 01 Nov 2017
TL;DR: Leveraging the sequential-only write property of shingled devices, this paper proposes a new shingle aware persistent cache cleaning policy for DM-SMR drives, which delivers better performance (by up to 2.5X) via dramatically reducing write amplification associated with persistence cleaning and alleviating fragmented reads.

I and i
TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.

Extraordinary optical transmission through sub-wavelength hole arrays
Thomas W. Ebbesen,Thomas W. Ebbesen,Henri J. Lezec,H. F. Ghaemi,Tineke Thio,Peter A. Wolff,Peter A. Wolff +6 more
TL;DR: In this article, the optical properties of submicrometre cylindrical cavities in metallic films were explored and it was shown that arrays of such holes display highly unusual zero-order transmission spectra at wavelengths larger than the array period, beyond which no diffraction occurs.

Theory of Diffraction by Small Holes
TL;DR: In this paper, the diffraction of electromagnetic radiation by a hole small compared with the wave-length is treated theoretically, and a complete solution is found satisfying Maxwell's equations and the boundary conditions everywhere.

Light in tiny holes
Cyriaque Genet,Thomas W. Ebbesen +1 more
TL;DR: The presence of tiny holes in an opaque metal film leads to a wide variety of unexpected optical properties such as strongly enhanced transmission of light through the holes and wavelength filtering, which are now known to be due to the interaction of the light with electronic resonances in the surface of the metal film.
