    摘要: A primary optical disk recording apparatus comprises a first light source for recording a signal on a primary optical disk, an objective lens for converging a light beam from the first light source on the primary optical disk, a second light source for detecting a focus error between the objective lens and the primary optical disk, and a controller for detecting a reflection light beam from the first light source, which is reflected from the primary optical disk, while the signal is being recorded on the primary optical disk, and for subjecting a signal of the reflection beam to an arithmetic operation process, thereby detecting a first focus error signal and controlling the focus error on the basis of the first focus error signal.

    摘要: An optical disk has first and second substrates, at least one of which is provided with optically readable pits corresponding to record data, and a reflection film coated on the pits. In the optical disk, the first and second substrates are laminated on each other such that the surface on which the pits are formed, is located inside. Label information, indicative of the record data, is formed on at least one of the surfaces of the first and second substrates, which contact each other.
