Magnetic Recording

With the rapid advancement of IoT, digital transformation (DX), and generative AI, the volume of digital information handled worldwide is increasing explosively, creating strong demand for ever-larger data center storage capacities. Hard disk drives (HDDs) are currently used as the primary storage medium in data centers, and owing to their non-volatility, low cost, and large capacity, HDDs are expected to remain in use for the foreseeable future. As a major recent technological breakthrough, heat-assisted magnetic recording (HAMR), which raises the temperature of the recording medium during the write process, was commercialized in 2020, and mass production began in 2024. In academia, leading research has been conducted on high-density HAMR recording and novel magnetic recording concepts, and this presentation will introduce some representative examples of these advances.
