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.Ībstract: A method for forming a protective bilayer on a magnetic read/write head or magnetic disk. 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. 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. The bilayer is formed as an adhesion enhancing underlayer and a protective diamond-like carbon (DLC) overlayer.

Adjusting the values of x and y contributes to such qualities of the protective bilayer as stress compensation, chemical and mechanical stability and low electrical conductivity. The underlayer is a transition metal oxynitride, having the general formula MeOxNy, where Me represents a single element or an alloy of the following transition metal elements: Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, and W, here x can be within the range between 0 and 3 and y is in the range between approximately 0 and 2. COPYRIGHT: (C)2006,JPO&NCIPIĪbstract: A protective bilayer on a magnetic read/write head or magnetic disk is formed as an adhesion enhancing and corrosion resistant underlayer and a protective diamond-like carbon (DLC) overlayer. The number of crossover points that the first electrical trace has may equal the number of crossover points that the second electrical trace has. The conductive island area may electrically couple the first part of the first electrical trace to the second part. A conductive island area may be patterned into the support layer. The first electrical trace may be made of a first part on one side of the second electrical trace and a second part on the opposite side of the electrical trace. The second electrical trace crosses over the first electrical trace. SOLUTION: In one embodiment, the externally wireless laminated suspension has an insulating layer to electrically isolate a first and second electrical trace from a conductive support layer. The number of crossover points that the first electric path 330 has may be equal to the number of crossover points that the second electric path 340 has.Ībstract: PROBLEM TO BE SOLVED: To disclose an externally wireless laminated suspension for a hard disk drive.
