Magnetic tape is used for deep archival storage as a means of storing large amount of infrequently accessed data. Current magnetic tape media consists of a random assembly of small Ba-Ferrite particles encapsulated in a polymeric film coated on a 5 m

The effect of a 1.5 nm thick CoX layer (CAP) of high Curie temperature TC, deposited on top of an L10 Fe50Pt50 layer (MAG) on the properties of the MAG/CAP bilayer is investigated. Two series of samples are studied: “w/o CAP” are single MAG layer

We investigated the microstructure and magnetic properties of FePt-(C,SiO2) granular films deposited on MgO, MgTiO, and MgTiON underlayers. The coercivity and grain size of the FePt-(C,SiO2) film are substantially degraded when deposited on the MgTiO

FePt granular films with grain size smaller than 10 nm are promising candidates for storage media used in the next generation heat-assisted magnetic recording technology. However, FePt films show degraded magnetic properties when the grain size is re

The ac susceptibility of heat-assisted magnetic recording media was measured from room temperature to 750 K for the frequencies ranging from 500 Hz to 50 kHz. Using an analytical model for the ac susceptibility of weakly interacting uniaxial superpar

Heat-assisted magnetic recording (HAMR) is a promising approach for enabling large increases in the magnetic data storage density. Amorphous carbon is the principal overcoat material of thin-film disks and magnetic heads in the HAMR systems. In this

The potential benefits of patterning discrete tracks onto a disk for magnetic data storage have long been investigated. A practical process for manufacturing a cost-effective discrete track recording (DTR) medium has prevented such a disk from being

Silicon oxide pillars with tunable feature sizes and pitches are fabricated based on a block copolymer self-assembly template. By using reactive ion etching (RIE), the feature size of the silicon oxide pillars can be tuned without affecting the pitch

Discrete track recording (DTR) media provides the potential for improving recording performance due to the inherent inter-track isolation that it provides which can result in improved signal-to-noise ratio (SNR). Various methods for producing DTR med
