Since the temperature difference between the high temperature part and the low temperature part does not become large, it is possible to prevent the amount of contraction between the high temperature part and the low temperature part. As a result, the thickness of the disk substrate can be made uniform, and the quality of the disk substrate can be improved.
- the present invention can be used for a disk substrate manufacturing apparatus for manufacturing a disk substrate.
