    摘要: A disk-layer-configuration judging unit (180) of a recording-and-reproducing apparatus (100) judges which of a one-layer disk (10) and a two-layer disk (20) is a disk in which content data is to be recorded. A system controller (280) sets a recording rate to be a conventional recording rate when the disk-layer-configuration judging unit (180) judges that the disk is the one-layer disk (10) while setting the recording rate to be a recording rate that makes the maximum recordable time twice as much as the maximum recordable time of the one-layer disk (10) when the disk-layer-configuration judging unit (180) judges that the disk is the two-layer disk (20).

    摘要: In a disk player which plays a disk having first and second areas in which the same contents are recorded with different amounts of information, the disk player includes a playback unit that reads disk information to play the disk, a storage unit that stores disk management information relating to the first and second areas when starting playback of the disk, and a switching instruction unit that, while one area of the first and second areas is played, instructs to play the other area. In response to the switching instruction unit, the disk management information relating to the other area is read from the storage unit, and thus playback of the other area starts.

    摘要: Provided is a method of manufacturing a magnetic disk glass substrate, wherein, in a main surface polishing process, main surface polishing is applied to one of main surfaces of a glass substrate so that the one main surface has a predetermined arithmetic mean roughness, and main surface polishing is applied to the other main surface of the glass substrate so that the other main surface has a roughness which is higher than the arithmetic mean roughness (Ra) of the one main surface and which is low enough to prevent a component forming the magnetic disk glass substrate from being eluted from the other main surface.
