Abstract: CoCrPtB is a conventional material used in some of the layers of a thin film magnetic media structure used for recording data in data storage devices such as hard drives. Typically the CoCrPtB layers used for magnetic media have high Cr and low B in bottom magnetic layers and low Cr and high B in top magnetic layers. In accordance with one embodiment of this invention and to improve media electrical performance, fifth elements, such as Ta, Nb and Hf, etc. were added to the CoCrPtB materials, resulting in CoCrPtB-X, to enhance the grain segregation. The five element CoCrPtB-X layers were deposited using a pulsed direct current sputter technique instead of conventional direct current sputtering techniques. The resulting magnetic media structure having CoCrPtB-X alloy layers exhibits an increase in coercivity Hc and improvement in recording performance.

Abstract: In this invention, an ultra thin layer of CoCr alloy nucleation layer is sputtered at an extremely low deposition rate above a predominantly (200) oriented Cr film followed by a CoCrPt based alloy sputtered film at higher rates and moderate temperatures. This structure creates a media which has very high Hc, and excellent PW50, low noise and excellent low TNLD values. By using this technique, the CoCrPt magnetic film achieves excellent in-plane crystallographic orientation, and high Hc is achieved with minimal amount of Pt addition to the magnetic film. The method allows very fine grain structure of cobalt to be formed which contributes to good signal to noise ratio. A fine grain structure combined with chromium segregation between the grains improve the signal to noise ratio even more. A high degree of in-plane c-axis orientation is achieved in the cobalt layer which provides very high hysteresis loop squareness which helps to improve the OW and TNLD.
