Book excerpt: The HCP CoCrPtO Perpendicular magnetic recording media are attractive to achieve recording densities over 1 Tbit/in2 owing to their low media noise characteristics. Structural refinement is critical to the development of ultra-high recording density perpendicular media with low noise. The grain size and film thickness are on a scale of 8 nm and 20 nm or less, respectively, so it is evident that high-resolution transmission electron microscopy (HRTEM) is the most powerful method to characterize the nanoscale structural features and elucidate their effects on the magnetic recording media performance.
