Abstract
A first substrate is formed to include a surface on which a first record layer is formed, and which includes an inner circumferential portion on which a ring-shaped member is provided. Ultraviolet curing resin is dropped onto part of the surface which is located inward of the ring-shaped member, and the first substrate is then spun to coat the first record layer with the ultraviolet curing resin. Furthermore, a second substrate is formed to include a surface on which a second record layer is formed, and the second substrate is spun to coat the second record layer with ultraviolet curing resin. Then, the first and second record layers are made to face each other, and the first and second substrates are bonded to each other by the ultraviolet curing resin.
