Coating Application Case: "Hard Disk Slider"

Introduction of examples of ultra-thin film technology aimed at achieving dramatic performance improvements in hard disk drives.

To achieve a dramatic improvement in the performance of hard disk drives, the thinning of the slider head protective film has been considered. With the nano-spacing of the head and disk, a harder and more elastic carbon film is required to minimize wear caused by contact between the head and the disk surface, leading to the demand for a dense film with excellent corrosion resistance and no pinholes. The ta-C film produced by the FCVA coating method has been widely adopted in the industry as a carbon film that meets these performance requirements and offers excellent productivity while being particle-free. 【Application Examples】 ○ Conventional DLC films posed practical issues in the thin film region below 4nm. ⇒ The use of ta-C films has enabled the practical application of 1.5nm thin films. ○ In vertical magnetic recording systems, the application of ta-C films as a disk surface protective film is also being considered. ⇒ Challenge: There is a need for faster coating compared to sliders.
