Showa Denko Starts Shipment of Newly Developed HD Media for Record-breaking 26TB Near-line HDD

Tag: Other

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 designed for high-density magnetic recording beyond 1TB/in2, 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 spread of cloud-computing service and increase in video content, data centers need HDDs with larger storage capacity. In the field of HD media, which are key part of HDDs and affect their storage capacities, the Showa Denko Group has been putting topflight products in the world onto the market before others. As the largest independent HD media supplier, the Showa Denko Group will continue contributing to the increases in storage capacities of HDDs in accordance with its motto of “Best in Class,” thereby supporting expansion of data economy.

*1: As of May 9, 2022
*2: Energy-assisted magnetic recording is a technology to record data on the surface of HD media with density higher than those achieved through conventional recording technologies, by pouring energy into magnetic substances which have high coercivity and assisting reversal of magnetization.
*3: Shingled magnetic recording is a technology to record data on the surface of HD media with high density by piling up a part of magnetic layers one another like singles.

news | 10 March 2022
Tag: Business Other

Showa Denko K.K. (SDK) (TOKYO: 4004) announces that it was resolved at the Board of Directors meeting held today that SDK will set the firm name of a new company (the newly integrated company) which is planned to be organized in January 2023 as a result of integration of SDK and Showa Denko Materials Co., Ltd. (SDMC), which is a member company of the Showa Denko Group, as in below. Execution of this resolution is subject to adoption of relevant resolutions by shareholders at an extraordinary general meeting of shareholders of Showa Denko K.K., which is planned to be held in late September 2022, and is also subject to adoption of relevant resolutions by shareholders at an extraordinary general meeting of shareholders of SDMC, which is planned to be held in late September 2022.

We will announce the details of this matter including changes in articles of incorporation as soon as they are decided.

1. Firm name of the Newly Integrated Company

Resonac Corporation

As stated in the news release titled “Showa Denko Group Starts to Consider Transformation into Holding Company Structure,” which is announced at the same time today, we will consider transformation of our company structure from the current one into holding company structure. In this plan, we will set the current Showa Denko K.K. as a company to be split, execute the company split, make Showa Denko Materials Co., Ltd. (SDMC), which is a wholly owned subsidiary of HC Holdings K.K. (HCHD), in which SDK holds 100% of voting rights, succeed all businesses currently operated by SDK, and merge HCHD into SDMC. Then we will set SDMC as a company to be split, execute the company split, and make SDK succeed a part of SDMC’s assets and liabilities.

If execution of this plan is finalized, firm names of the holding company and the manufacturing company will be set as follows.

Holding company (current Showa Denko K.K. (planned)): Resonac Holdings Corporation
Manufacturing company (current Showa Denko Materials Co., Ltd. (planned)): Resonac Corporation

2. Corporate logotype

3. Reason for change in the firm names

In January 2023, SDK and SDMC will cooperatively transform themselves into a holding company structure, in which the holding company will specialize in formulating and executing group strategy, and functioning as a company listed on the stock exchange, and the newly integrated company (a company involved in manufacturing) will focus on strengthening competitiveness of each business of the Company in order to realize synergy of integration of SDK and SDMC as soon as possible, and operating businesses in a quick and flexible manner corresponding to the surrounding environment. The newly organized corporate group will aim to become a “Co-Creative Chemical Company,” which will have global top-level competence as a chemical manufacturer, make decisions and act swiftly and flexibly, and co-create better society with key players in various industries and consumers who share a high aim and ideal with us. In order to take a new step as the newly integrated company and realize Co-Creative Chemical Company, we decided to change the new company’s name into “RESONAC” concurrently with the integration of the two legal entities.

The Showa Denko Group sees the integration as “the second foundation” for SDK and SDMC. Under the new firm names, the brand-new Resonac Group will ferment the sense of unity further, create new functions required of the time as an advanced material partner, and contribute to sustainable development of global society.

4. Our hope put into the new firm name and corporate logotype

The new firm name “RESONAC” was created as a combination of two English words, namely, the word of “RESONATE” and “C” as the first letter of CHEMISTRY. Into RESONAC, we put our hope that the Group’s wide-ranging and flexible advanced material technologies will be connected and resonate with our partners’ various technologies and ideas to realize bright future, and the resonance will spread further to meet new partners, thereby creating a powerful surge that changes society.

To express this hope of ours, we put two parallel lines that rises steadily from left to right into the lower left of the first letter R in the new corporate logotype. These parallel lines symbolize co-creation borne by resonance, and also symbolize our strong will to spread the resonance further and challenge to realize bright future together with our partners.

5. The scheduled date of changes in firm names

January 1, 2023
