在面心立方Pt和Au衬底上沉积的CoCrTa薄膜具有良好的c轴取向性。外延生长机制可以解释这种效应的起源。研究了这种介质的垂直MOKE和VSM介电常数、磁滞回线形状和接触记录结果，并结合薄膜结构进行了讨论。采用接触式磁头的单层Pt/CoCrTa刚性盘实现了160 kFRPI的第一个峰值D_（50）。
CoCrTa films deposited on fcc Pt and Au underlayers show excellentc-axis orientation. The ‘epitaxial-growth’ mechanism may explain the origin of such an effect. The perpendicular MOKE and VSM coercivity, shape of hysteresis loops and contact recording results of such media are investigated and discussed together with the film structure. A first peakD50of 160 kFRPI has been realized by a single-layer Pt/CoCrTa rigid disk using an in-contact MIG head.
