    摘要： A magnetic disk is protected by a bilayer. The bilayer is formed as an adhesion enhancing underlayer and a protective diamond-like carbon (DLC) overlayer. The underlayer is formed of an aluminum or alloyed aluminum oxynitride, having the general formula AlOxNy or MezAlOxNy where Mez symbolizes Tiz, Siz or Crz and where x, y and z can be varied within the formation process. By adjusting the values of x and y the adhesion underlayer contributes to such qualities of the protective bilayer as stress compensation, chemical and mechanical stability and low electrical conductivity. Various methods of forming the underlayer are provided, including reactive ion sputtering, plasma assisted chemical vapor deposition, pulsed laser deposition and plasma immersion ion implantation.

    摘要： A method for forming a protective bilayer on a substrate that is a magnetic read/write head or a magnetic recording medium. The bilayer is formed as an adhesion enhancing and corrosion resistant underlayer and a protective diamond-like carbon (DLC) overlayer. The underlayer is formed of silicon oxynitride, having the general formula SiOxNy, where x can be within the range between 0.02 and 2.0 and y is in the range between approximately 0.01 and 1.5. By adjusting the values of x and y the underlayer contributes to such qualities as strong chemical bonding between the substrate and the DLC, wear and corrosion resistance, chemical and mechanical stability and low electrical conductivity. The underlayer may be formed by various methods such as reactive ion sputtering, plasma assisted chemical vapor deposition, reactive pulsed laser deposition, plasma surface treatment and plasma immersion ion implantation.

    摘要： A system and method for adjusting the flying height of a magnetic head above a magnetic storage medium, such as a disk, is disclosed. A charging surface of the slider, separate from the read/write head, allows a charging electrical interconnect to apply an electrical charge to the slider. By acting as a quasi-parallel capacitor, the amount of spacing in the head-disk interface may be increased or decreased based on the amount of voltage applied. The slider may be electrically isolated from the suspension. Simultaneously, a heating element deforms the slider to further adjust the spacing between the read/write head and the disk surface. A feedback control system may monitor and control the head-disk spacing by measuring a temperature or other environmental conditions surrounding the slider and disk.
