Title: Innovations of Tai-hwang Lai in Magnetic Recording Media
Introduction
Tai-hwang Lai is a notable inventor based in Hsin-chu, Taiwan. He has made significant contributions to the field of magnetic recording media, holding two patents that enhance the performance and efficiency of hard disk drives. His work focuses on developing high-density recording mediums that improve data storage capabilities.
Latest Patents
Lai's latest patents include a CoCrNiTa/Cr magnetic recording medium designed for high-density computer hard disks. This innovative medium consists of an aluminum or Ni/P substrate, a chromium underlayer, a four-component magnetic recording layer, and a carbon protective layer. The magnetic recording layer is composed of 66-78 atom percent cobalt, 12-16 atom percent chromium, 6-10 atom percent nickel, and 4-8 atom percent tantalum. This design results in high coercivity, exceeding 2,800 Oe, which enhances recording density, reduces noise, and improves off-track capability. Additionally, it allows for sputtering at lower temperatures.
Another significant patent involves high-coercivity magnetic recording media used in hard disk drives. This medium features a nonmagnetic substrate, a NiAl alloy seed layer, a CrV alloy sublayer, a CoCrPtTaNb alloy magnetic layer, and a carbon overcoat. This structure improves the signal-to-noise ratio, coercivity, overwrite capability, and orientation ratio, significantly enhancing storage density and read/write capacity. The coercivity of the magnetic layer can reach up to 4,000 Oersteds, even without the NiAl seed layer.
