Information Degradation during Archiving in Heat-Assisted Magnetic Recording

Characterization of Heat-Assisted Magnetic Recording Channels

The storage capacity of hard disk drives has increased tremendously over the last decade. However, the rate of increase has reached a bottle-neck as the technology approaches a theoretical limit known as the super-paramagnetic limit. Heat-Assisted Magnetic Recording (HAMR) has emerged as one of the important technologies to overcome this limit. The process of heating while writing brings about ...

Patterned 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...
