Expanding Hard Disk Media Production Capacity in Response to Growing Storage Demand

Resonac Corporation (President and CEO: Hidehito Takahashi, hereinafter “Resonac”) announced that it will expand its production capacity for hard disk media from the current level of approximately 160 million disks to about 210 million disks annually, representing a 31% increase. The company will position its group company, Resonac HD Singapore Pte. Ltd. (RHDS), as the core production hub and plans to gradually launch additional production lines from 2027 onward, in line with market trends and demand.

Demand for data center storage is expected to grow over the medium to long term, driven by the rapid adoption of generative AI and cloud services(1). In particular, nearline(2) hard disk drives (HDDs)—known for their high reliability, large capacity, and cost efficiency—are expected to continue playing a central role in data storage infrastructure. In response to these market conditions, Resonac will restructure and expand its production capacity across the group to strengthen its stable supply of hard disk media. At RHDS, the company will introduce new production equipment by utilizing both existing and currently idle floor space. To enhance investment efficiency, certain idle equipment from facilities that have been closed, including the company’s former site in Taiwan, will be relocated to RHDS as part of the capacity expansion.

Looking ahead, Resonac will continue evaluating further production capacity increases in response to market growth and expanding customer needs. Through the development and supply of hard disk media with industry-leading recording density, the company aims to support digital infrastructure—including data centers—and contribute to the advancement of a highly digitalized society.

*2 Nearline: A category of large-capacity storage used primarily in data centers. While data remains accessible online at all times, nearline storage is typically used for large volumes of data with relatively low access frequency—such as backups and cloud data—rather than data requiring frequent high-speed access.
