Substrates for Thin-Film Magnetic Heads in Hard Disk Drives (HDDs)Hard Disk Drive (HDD) head substrates are suitable for ultra-high-precision processing.
We supply substrates suitable for heads with low-fly height, enabled by ultra high-precision processing such as ion milling and reactive ion etching, for the increasing area density of hard disk drives (HDDs).
