摘要：

KOBELCO's aluminum substrate products, which currently command more than 50% market of the global market, are widely used in high-density, advanced magnetic disks. High-quality magnetic disks demand optimal alloys, the critical control of intermetallic compounds morphologies, and a highly sophisticated level of production technology. Though future alternative substrate development for advanced hard disk drives (HDD) is currently being researched worldwide, cost-effective aluminum substrates, which are widely available, will continue to dominate this fast-growing, important market.
