Abstract
A method for producing an optical recording medium including a step of coating a dye solution on a substrate by a spin coating method to form a dye recording layer, wherein the substrate is rotated at a rotation speed of 400 rpm or higher during a period from the beginning to the end of the supply of the dye solution.

A method for producing an optical recording medium comprising the steps of:
- supplying a dye solution;
- and
- coating the dye solution on a substrate by a spin coating method to form a dye recording layer,
- wherein the substrate is rotated at a rotation speed of 400 rpm or higher during a period from the beginning of supply of the dye solution to the end of supply of the dye solution.

A method for producing an optical recording medium comprising the steps of:
- supplying a dye solution;
- coating the dye solution on a substrate by a spin coating method;
- and
- drying the dye solution to form a dye recording layer,
- wherein the method has, in a sequence from the beginning of the supply of the dye solution to the completion of the drying, a low-speed rotation step of rotating the substrate at a speed lower than a speed at the beginning of the supply of the dye solution or than a speed at the end of the supply of the dye solution.
