Effects of orientation on thin-film media, read/write characteristics

Effects of easy orientation on the read/write characteristics of CoCrTa longitudinal media are measured. The dependence of the single-transition noise power on the recording density has a peak at high density, and the peak value increases as the coercivity orientation ratio increases. However, the s...

Description
Summary:Effects of easy orientation on the read/write characteristics of CoCrTa longitudinal media are measured. The dependence of the single-transition noise power on the recording density has a peak at high density, and the peak value increases as the coercivity orientation ratio increases. However, the single-transition S/Nd becomes larger throughout the recording density as the coercivity orientation ratio increases. Increasing the Cr concentration is effective for reducing the single-transition noise power, but it has little effect on increasing the output signal. The effects of orientation for media of different Cr concentrations are compared at different recording densities.< >
