TOKYO, Feb 21, 2019 - (JCN Newswire) - Showa Denko (SDK; TSE:4004) will begin shipment of newly developed 3.5-inch HD media this year based on the Microwave Assisted Magnetic Recording (MAMR) technology for next-generation hard disk drives (HDDs).

This new product has been adopted by Toshiba Electronic Devices & Storage Corporation for use in its MAMR-technology-based 18 terabyte near-line HDD, which represents the largest storage capacity in the industry. Toshiba will begin sample shipment this year. SDK's new HD media has storage capacity of 2 terabyte per disk, and uses aluminum substrate.
