摘要：
A recordable optical disk is provided with: a disk substrate having a recording surface; a track portion, which is coaxially or spirally arranged on the recording surface, and to which the information is recorded by irradiating a light beam modulated in correspondence with the information, thereonto; and an interval portion disposed on the recording surface between adjacent turns of the track portion on the recording surface. The reflection coefficient of the interval portion is higher than the reflection coefficient of the track portion.
