Spin coater, temperature controlling method of the same, optical disc production apparatus, and optical disc production method

An optical disc production apparatus comprising:

• a spin coater,
• wherein the spin coater comprises:
• a rotation table that rotatably holds a disc substrate,
• a spin-cup that surrounds the outer circumference of the disc substrate held on the rotation table,
• a dripping unit configured to drip an ultraviolet-curable resin composition onto a surface of the disc substrate,
• a rotating unit configured to rotate the disc substrate via the rotation table to spread the ultraviolet-curable resin composition over the surface of the disc substrate,
• a heating unit configured to heat the ultraviolet-curable resin composition on the disc substrate, and
• a temperature controlling unit configured to control a reaching temperature of the spin cup, which is increased by the heating unit each time the ultraviolet-curable resin composition is spread, so as to be constant over multiple spin coating processes, and
• wherein a cover layer is formed using the spin coater.
