Kind Code:
A
Abstract:
A description is given of a method of manufacturing a stamper for use in the manufacture of Small Form Factor (SFF) optical data storage media. A conventional master plate (2) is provided with a series of areas with spiral- or concentric-shaped information tracks (3a - 3h), having a relief structure, with the center of each area (3a - 3h) being located outside the axis of rotation (9) of the master plate (2). This is done by using a conventional master recorder and a separate master plate support structure (1) without the necessity for complex movements of the master recorder writing head. The master plate (2) thus obtained is used to produce the stamper, containing a negative replica of the surface of the master plate (2).
