「In the HDD-related field, development of CLA (Co-Located Actuator) and TSA (Triple Stage Actuator) suspensions for high-capacity data-center HDDs with 9 disks has been completed, and the company is rolling out overseas mass-production equipment that improved production efficiency by 20%. Development of CLA/TSA suspensions for HDDs with 10 disks is continuing.」
For 9-disk CLA/TSA products, development has been completed and the company has progressed to overseas deployment of equipment that improved production efficiency by 20%. Development of 10-disk products is continuing, representing further progress. - FY2020AdvancedAnnual report
「For 9-disk TSA products, the company established mass-production equipment that improved production efficiency by 20% and began mass production. For 10-disk TSA products, prototype optimization of resonance and swage characteristics is almost complete, and further optimization is under way.」
For TSA products for higher-capacity HDDs, the company established mass-production equipment for 9-disk products that improved production efficiency by 20% and began mass production. Optimization of prototypes for 10-disk products is also progressing. - FY2018First statedAnnual report
「To solve these 2 problems, a TSA (Triple Stage Actuator) combining a CLA suited to high-frequency positioning and a Milli-DSA suited to low-frequency positioning is required. Alongside development of these products, the company is also working on production technology and development to improve quality and reduce costs.」
The company is developing TSA products and production technology to address high- and low-frequency vibration in data-center HDDs by combining CLA and Milli-DSA.
