In the Heat Assisted Magnetic Recording (HAMR) process, the storage medium is temporarily heated during writing. This allows for increased areal densities since it enables the use of high anisotropy materials in the storage medium. In order for HAMR to be successful, a number of technical challenges must be overcome in the head and media and integrated into a low cost and reliable system. This integration must be compatible with existing thin film magnetic recording fabrication techniques including thin film wafer processes, slider lapping, and head/gimbal assemblies. In this presentation, a demonstration of 200Gb/in2 areal density recording will be shown as well as a path to increased areal density capability using Near Field Transducer (NFT) technology.
