Effect of in-plane and out-of-plane crystallographic orientation on thermal stability and recording characteristics of CoCrPtB alloy

Summary form only given. It has been reported that media with high in-plane orientation ratio (OR) may enhance thermal stability and strong in-plane orientation of the Co c-axis in isotropic glass media is needed to improve recording performance. In this work, a systematic study of thermal stability and recording characteristics was performed on glass media with varying in-plane crystallographic orientation [random 2D-to-3D] and preferred orientation [(10.0) vs (11.0)]. In addition, the effect of in-plane OR on thermal stability was investigated for the media deposited onto both mechanically textured and non-textured polish only AlNiP substrates.
