摘要：

Plasmonic devices are capable of efficiently confining and enhancing optical fields, serving as a bridge between the realm of diffraction-limited optics and the nanoscale. Specifically, a plasmonic device can be used to locally heat a recording medium for data storage. Ideally, the recording medium would consist of individually addressable and non-interacting entities, a configuration that has been regarded as the ultimate future hard-drive technology. Here, we describe a plasmonic nano-antenna that is fully integrated into a magnetic recording head and its use for thermally assisted magnetic recording on both continuous and fully-ordered patterned media using nanosecond pulses in a static tester configuration. In the case of patterned media at 1.5 Pb m(-2) (similar to 1 Tb inch(-2)) with 24-nm track pitch, we show ideally written bits without disturbing neighbouring tracks. We find a dramatic improvement in track width and optical efficiency compared to continuous media and show that this is largely due to advantageous near-field optical effects.
