Abstract
Noise characteristics on continuous plated thin-film media have been studied, using plated disks and Mn-Zn ferrite heads. It was found that the magnetic medium noise was influenced by magnetic medium underlayer properties and magnetic properties of the magnetic medium itself. The influence from the underlayer is considerably decreased by a gold film (0.1-μm thick) inserted between the underlayers. Medium noise power N2 from the magnetic medium itself is linearly proportional to half pulse width W50 and recording density 1/L (N2∝k⋅W50⋅1/L; k: constant; L: bit length). Noise in the γ-Fe2O3 particulate medium appears mainly in regions outside magnetic transition. However, the experimental result shows that noise in a continuous thin-film medium itself is caused by magnetic transition regions.
