Heat Assisted Magnetic Recording (HAMR) is a method that allows for storage of data on a magnetic recording medium at greater densities than are currently seen. Near field transducer needs to be able to efficiently focus light to very small spots (and hence provide very small thermal spots). Systems have been demonstrated where the source of optical energy was an off-slider source (i.e. external laser). There is a need to bring this light source to the slider itself. The advantages being increased efficiency and a full integrated HAMR solution for magnetic data storage.
