摘要： A collimator system is disclosed for use in an in-line pass-by sputtering system during the fabrication of recording media to improve the data storage density and read/write performance characteristics of the media. The collimator system includes a collimator shield and a collimator honeycomb. The shield includes a rectangular tube having a flange and a frame at inner and outer ends, respectively. The various components of the shield in part serve to prevent possible contamination of substrates due to target atom accumulation on the chamber walls during the sputtering process. The collimator honeycomb is provided for blocking target atoms from contacting the substrate at low incident angles. The collimator honeycomb is comprised of a plurality of collimators which are identical to each other. In a preferred embodiment, the collimators have a hexagonal cross-section taken from a perspective perpendicular to the substrate. The collimators may also have other geometric shapes. It is also contemplated that more than one collimator honeycomb level be used in alternative embodiments.

摘要： High areal density magnetic recording media are formed with a thin CoCrTaOx intermediate layer which provides appropriate crystalline orientation and surface morphology for the nucleation and growth of a magnetic layer thereon having increased coercivity and high squareness, while avoiding high substrate heating temperatures. Embodiments include sputter depositing an intermediate layer comprising Co, about 10 to about 20 atomic % Cr and about 1 to about 6 atomic % Ta, at a thickness of about 1.5 to about 18 Å on a Cr or Cr alloy underlayer, allowing partial oxidation of the surface of the intermediate layer by residual oxygen in the sputtering system, and then sputter depositing a CoCrPtTa magnetic alloy layer thereon.

摘要： Reproducible texturing of magnetic recording media is enhanced by sputtering a buffer layer, such as Ni—P, on a nonmagnetic substrate, prior to sputtering a textured bump layer. A magnetic recording medium comprising a sputter textured metal layer and high coercivity is achieved by employing an underlayer, such as NiAl or FeAl, preferably a composite underlayer containing a chromium or chromium-alloy layer and a NiAl layer, on the sputter textured layer. Advantageously, the buffer layer, underlayer, textured bump layer, magnetic layer and carbon overcoat can be sputter deposited in a single apparatus.
