Plasmonic near-field transducer for heat-assisted magnetic recording
Plasmonic devices, made of apertures or antennas, have played significant roles in advancing the fields of optics and opto-electronics by offering subwavelength manipulation of light in the visible and near infrared frequencies. The development of heat-assisted magnetic recording (HAMR) opens up a new application of plasmonic nanostructures, where they act as near field transducers (NFTs) to lo...
متن کاملComparative study of optical near-field transducers for heat-assisted magnetic recording
Heat-assisted magnetic recording (HAMR), widely considered to be the next generation technology for high-density data storage devices, uses a tiny plasmonic antenna called a near-field transducer (NFT) to focus light down to a subdiffraction volume. This results in a temporary and local rise in temperature of the recording medium thereby reducing its coercivity, allowing the external magnetic f...

متن کاملCharacterization 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 ...
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...
