Showa Denko Starts Shipment of Newly Developed HD Media for Record-breaking 26TB Near-line HDD
TOKYO, May 26, 2022 - (ACN Newswire via SEAPRWire.com) - Showa Denko K.K. (SDK) (TOKYO: 4004) has started shipment of newly developed 3.5-inch hard disk media (HD media) to be used in 26 terabyte (TB) hard disk drive (HDD), which has the largest storage capacity the HDD industry has ever produced(1).The new HD media support 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 aluminum platter, we successfully developed HD media which have storage capacity of 2.6TB per platter, the largest one in the industry. Thus, the new HD media have pioneered the age of HD media having recording density of 1TB/in2 or higher, and we successfully combined technology to produce fine crystals of magnetic substance with technology to improve rewrite-cycle endurance on the surface of HD media, while maintaining compatibility with shingled magnetic recording (SMR). We will accelerate development of new HD media further, and aim to realize near-line HDD having storage capacity of more than 30TB by the end of 2023.Due to the ...
