Een doorbraak op het gebied van hard disk technologie in een Nederlands/Japans onderzoekproject:
zo lezen we op de homepage van een van de onderzoekers:News: All-optical Magnetic Recording with Circularly Polarized Light
[...] No external magnetic field is required for this opto-magnetic switching, and the stable final state of the magnetization is unambiguously determined by the helicity of the laser pulse. This finding, previously believed to be fundamentally impossible (click here to read why), reveals an ultrafast and efficient pathway for writing magnetic bits at record-breaking speeds. With the recent development of compact ultrafast laser systems and the successful incorporation of lasers in magnetic storage devices, the present demonstration of ultrafast all-optical magnetization reversal might spur the realization of a new generation of ultrafast magnetic recording devices.
