Showa Denko starts shipping

TOKYO, May 26, 2022 – (ACN Newswire) – Showa Denko KK (SDK) (TOKYO:4004) has started shipping a new 3.5 inch hard drive carrier (HD carrier) for use in a 26 terabyte hard drive (TB) (HDD), which has the largest storage capacity ever produced by the hard disk industry(1).

The new HD media supports Energy Assisted Magnetic Recording(2) and Shingled Magnetic Recording(3)(SMR). This time, by introducing Showa Denko Group’s latest magnetic layer design and technology to produce fine crystals of magnetic substance on the surface of the aluminum platter, we have successfully developed HD media which has a storage capacity of 2. 6TB per platter, the largest in the industry. Thus, the new HD media has pioneered the era of HD media having a recording density of 1TB/in2 or more, and we have successfully combined the technology to produce fine crystals of magnetic substance with technology to improve overwrite cycle endurance on the surface of HD media, while maintaining compatibility with Shingle Magnetic Recording (SMR). We will further accelerate the development of new HD media and aim to realize a near hard drive with a storage capacity of more than 30TB by the end of 2023.

Due to the spread of cloud computing service and the increase in video content, data centers need hard drives with larger storage capacity. In the field of HD media, which is a key component of hard drives and affects their storage capacities, Showa Denko Group has brought world-leading products to market before others. As the largest independent HD media provider, Showa Denko Group will continue to contribute to increasing hard drive storage capacities in line with its “Best in Class” motto, supporting the expansion of the data economy. .

*1: As of May 9, 2022
*2: Energy-Assisted Magnetic Recording is a technology for recording data on the surface of an HD medium with a higher density than that achieved by conventional recording technologies, by dumping energy into magnetic substances with high coercivity and by aiding the reversal of magnetization.
*3: Shingled magnetic recording is a technology for recording data on the surface of high-density HD media by stacking part of the magnetic layers on top of each other like singles.
