Claims
- 1. A method of treating a substrate of a recording medium, comprising:forming a solgel layer on the substrate and patterning the solgel layer with a pattern representing information, wherein the recording medium comprises a magnetic recording layer.
- 2. The method of claim 1, wherein a thickness of the solgel layer is in the range of about 0.3 to 1 μm.
- 3. The method of claim 1, wherein the forming the solgel layer on the substrate is by a spin-coating process.
- 4. The method of claim 1, wherein the patterning forms a pattern that represents a layout of servo sectors or tracks.
- 5. A method of treating a substrate of a recording medium comprising,forming a solgel layer on the substrate and patterning the solgel layer, wherein the recording medium comprises a magnetic recording layer and the patterning is by an embossing process.
- 6. A method of treating a substrate of a recording medium, comprising:forming a solgel layer on the substrate, patterning the solgel layer, sintering the solgel layer, polishing the solgel layer to produce a first surface and exposing the first surface to ozone produced by activating oxygen by protons to produce a second surface, wherein the recording medium comprises a magnetic recording layer sintering the solgel layer.
- 7. The method of claim 6, wherein the second surface has a Rmax value of less than 5 nm and a Ra value of less than 1 nm.
- 8. The method of claim 6, wherein the first surface has a maximum difference in height between the highest and lowest points on the first surface relative to a mean plane of less than 10 nm.
- 9. The method of claim 6, wherein the second surface has a maximum difference in height between the highest and lowest points on the second surface relative to a mean plane of less than 5 nm.
