    摘要: An optical disc recording apparatus (10) is provided with a tracking servo (13) for tracking a spiral track of concave and convex marks, an analog signal processor (14) for extracting a reproduction signal corresponding to the concave and convex marks, a digital signal processor (15) for extracting a channel clock synchronized with a channel bit length of the concave and convex marks, and a sub-information recording section (30) for recording sub-information by irradiating laser light based on the tracking to the spiral track. The sub-information recording section (30) records all the sub-information by repeating a process of recording a part of the sub-information by discretely irradiating laser light at a specified interval and with a specified frequency in synchronism with a channel clock by one tracking to form recordable marks on a reflective film a plurality of times. By this construction, a tracking control to the concave and convex marks can be stably executed and the sub-information can be stably recorded.

    摘要: To provide an optical disk device, an optical disk control method and an integrated circuit, which are capable of writing a recordable mark by changing the reflectance ratio of a reflective film formed on concave-convex pits without using an industrial special device or a high-power laser light source. A data reproduction controller (103) sets a first rotation speed in a disk rotation speed switching unit (108) and a first laser power in a laser power switching unit (107) when reproducing the concave-convex pits. When writing the recordable mark, a mark recording controller (104) sets in the disk rotation speed switching unit (108) a second rotation speed that is slower than the first rotation speed and the lowest rotation speed at which the concave-convex pits can be reproduced, and sets a second laser power greater than the first laser power in the laser power switching unit (107) in accordance with the emission timing.

    摘要: Provided is an optical disc having main information to be decrypted using sub information recorded thereon by arranging concave or convex recording marks in a spiral track wherein a reflective film is formed on the recording marks. First sub information is recorded and superimposed on the main information by shifting/deforming the recording marks or altering a pattern of the recording marks. Second sub information is recorded and superimposed on the main information by changing a reflectivity of the reflective film. The first and second sub information are recorded in an area from which the first and second sub information are to be read simultaneously. The second sub information is recorded in a manner to be associated with the first sub information. The first and second sub information are associated with each other and are recorded in the same area.
