Process of preparing a recording member having a variable thickness recording layer

摘要

A magnetic recording disk is constructed wherein a disk substrate is overlayed with at least one non-recording layer. A recording layer is then overlayed on the non-recording layer with the thickness of the recording layer at those areas corresponding to the inner track zone located toward the central hub area of the disk being thinner than the intermediate track zone radially displaced outwardly from the inner track zone toward the periphery of the recording disk.
