Signal Processing for Bit-Patterned Media and Heat-Assisted Magnetic Recording Systems with Media Noise
With the advent of the information age, the demand for larger storage capacity is ever increasing. However, the need to continue scaling conventional magnetic recording technologies to higher areal densities has led to physical and engineering limits which are difficult to overcome. New magnetic recording technologies are required. Bit-patterned media recording (BPMR) and heat-assisted magnetic...
متن کاملHeat-Assisted Magnetic Recording: Fundamental Limits to Inverse Electromagnetic Design
Heat-Assisted Magnetic Recording: Fundamental Limits to Inverse Electromagnetic Design by Samarth Bhargava Doctor of Philosophy in Engineering – Electrical Engineering and Computer Sciences University of California, Berkeley Professor Eli Yablonovitch, Chair In this dissertation, we address the burgeoning fields of diffractive optics, metals-optics and plasmonics, and computational inverse prob...
متن کاملPatterned medium for heat assisted magnetic recording
Heat assisted magnetic recording HAMR is a potential solution to extend the limits of conventional magnetic recording. In HAMR, the heating of the recording medium is achieved with a near-field optical transducer. Although the literature suggests novel transducers, there is little consideration of the optical and thermal aspects of the magnetic medium. In this letter we suggest a recording medi...
متن کاملMagnetic Layers for Perpendicular Recording Media
Hard disk drives (HDDs) are recently being incorporated into video recorders, car navigation devices, family game machines, etc., as devices (AV-HDDs) to store digital AV (audio-visual) information such as movies and television programs. Because the AV-HDD has the features of large capacity, high speed and low cost, it is suitable for long-time recording, high-speed random access and multi-chan...
متن کاملMagnetic structures in Co-Cr media for perpendicular magnetic recording
High bit densities have been demonstrated in longitudinal as well as in perpendicular magnetic recording. For the latter an area density of more than 12 G b i t / i n 2 has been obtained in a sputtered C o C r T a hard disk with a soft magnetic underlayer recorded with a special single pole head. In this paper the role of microstructure and morphology in relation to the compositional separation...
