Abstract: An information recording and playback device includes a recording and playback unit, and a controller. The controller divides a recording area of an optical disk into a first recording area which is at an inner circumference side, and a second recording area which is at an outer circumference side. The controller controls the recording and playback unit such that the unit records or plays back data in the first recording area at a first speed, and records or plays back data in the second recording area at a second speed slower than the first speed. The predetermined radius is set to a boundary between an area in which a control residual exceeds a predetermined reference value when servo control related to focusing and tracking is performed on the recording area of the optical disk, and an area in which the control residual does not exceed the predetermined reference value.

Abstract: In an optical disk manufacturing apparatus, a movement mechanism changes the movement speed of a laser beam irradiation component from a first to a second speed at a first radial position located within where the laser beam irradiation component moves from an inner peripheral region of the optical disk to an identification information recording region of the optical disk, and changes the movement speed from the second to a third speed at a second radial position at which the laser beam irradiation component has reached the identification information recording region at the second speed. The second speed is lower than the first speed and the third speed. The laser beam irradiation component records the identification information by irradiating with a laser beam while alternating between a first power level and a second power level low enough not to crystallize the recording layer, when moving through the identification information recording region.

Abstract: A method for enhancing recording yields by monitoring dye polymer formation on a glass substrate is provided. After the glass substrate is coated with a dye polymer layer and before pits are formed on the dye-polymer coated glass, the dye polymer coated glass substrate is scanned to detect defects. The dye-polymer coated glass is discarded on the one hand if the defects detected through the scanning are at or above an unacceptable threshold level, and on the other hand data is written on the dye-polymer coated glass if the defects detected through the scanning are below the unacceptable threshold level.

Abstract: An optical media disk is treated with a light-sensitive material that impedes the ability of an optical media player from reading data stored on the disk. This light-sensitive material is a material that changes phase upon exposure to one or more wavelengths of light. During the initial phase, the light-sensitive material will render the disk unreadable. After activation, however, the disk becomes permanently readable by conventional optical media players. In this fashion, theft of yet-to-be-activated optical media is deterred.

Abstract: A disk has a plurality of recording layers in a laminated direction. When a defect occurs in any one of recording layers during disk manufacture, information about the defect is recorded in a read-only region in the recording layer. An optical disk apparatus determines which of the recording layers is usable based on the information about the defect read from the disk, and executes a recording/reproducing operation according to a determination result. Therefore, even when a disk with a defect in the recording layer is used, that disk may be offered to a user as an appropriately usable disk.

Abstract: A multilayer optical recording medium having three or more information recording layers is irradiated with a laser beam, and a first signal obtained from the reflected laser beam is subjected to a frequency filter. A second signal obtained by filtration through a high-pass filter is used to evaluate the characteristics of the multilayer optical recording medium. In this manner, even in a multilayer optical recording medium having three or more information recording layers, the influence of the variation of the thickness and material of the information recording layers and the influence of the variation of the thickness of a spacer layer can be clearly determined and evaluated.

Abstract: A method for inspecting an optical information storage medium includes irradiating the medium with a laser beam and rotating the medium by a constant linear velocity control technique by reference to the radial location at which the laser beam forms a spot on the medium; changing the rotational velocities according to the radial location on the medium between at least two linear velocities; generating a focus error signal and/or a tracking error signal based on the light reflected from the medium; performing a focus control and/or a tracking control on the laser beam based on the focus and/or tracking error signal(s); and passing the branched outputs of control loops for the focus and/or tracking error signal(s) through predetermined types of frequency band-elimination filters to obtain residual errors of the focus and/or tracking error signal(s) and comparing the residual errors to predetermined reference values.
