| 摘要 |
The invention relates to a method for the production of glass substrates for electronic storage media, comprising the following steps: Production of a pressed glass blank, the outer diameter of which corresponds to the outer diameter of the glass substrate for storage media, dressing the surface of the substrate by means of lapping and polishing processes and/or grinding by means of lapping kinematics. The invention is characterised in that during the pressing process, the introduction of the inner aperture and the individual dressing processes, no microscopic cracks are produced which limit the function of the electronic storage medium and thus the chemical tempering step for stabilisation of the microscopic cracks is not required. |
