The disc is one of a number of multilayer optical discs, which are designed so that information stored is retrievable from any of the discs by irradiating the disc with a light beam having the same wavelength and which have been classified into multiple groups. According to this method, performed first is Step (A) of measuring either a distance from a first one of multiple information layers of the given multilayer optical disc to a second one thereof, which is located adjacent to the first information layer, or a distance from the first information layer to the surface of the optical disc. Next, Step (B) of determining, by the distance measured, what group the given multilayer optical disc belongs to is performed.

In a recording medium including stacked recording layers, management data requiring reliability is recorded in the recording layer far from the surface of the recording medium and data bodies are recorded in the recording layer close to the surface of the recording medium. Thus a data file can be read even if defects such as fingerprints and scratches occur on the surface of the recording medium.

The layer-to-layer jump control sectionshifts the focus position of the light beam from that non-target storage layer to the target layer by reference to information indicating which of the multiple storage layers the non-target storage layer is.

An optical disc apparatus according to the present invention includes: a laser light source for emitting multiple light beams, of which the wavelengths are different from each other and include a first wavelength and a second wavelength that is longer than the first wavelength; an optical system for converging an arbitrarily selected one of the light beams on an optical disc that has a surface and at least one information storage layer; a focus control section for controlling the focus position of the light beam with respect to the optical disc; and a defect detecting section, which senses light reflected from the surface of the optical disc with the focus position of the light beam set on the surface, thereby determining, based on the intensity of the reflected light, whether or not there is a fingerprint on the optical disc.

Optical disk device

The optical disc apparatus of this invention includes: an optical pickup, which irradiates an optical disc with a light beam and generates a light detection signal based on the beam reflected from the disc; a search section, which controls the pickup before data is written on a storage area of the disc, thereby adjusting the beam spot location and searching a reference one of information layers stacked for a defective area in the storage area of the disc; a defect decision section for detecting an error based on the detection signal and determining a portion of the storage area, where the error has occurred, as the defective area; a defect size measuring section for measuring the size of the defective area in an area of the reference layer and generating a defect information list indicating there is the defective area in the area of the reference layer; and a recording range control section for managing, by reference to the list, the storage area such that no data will be written on a perpendicularly projected area defined by projecting the defective area of the reference layer perpendicularly to another information layer.

Optical disc device

An optical disc drive according to the present invention can read and/or write data from/on an optical disc with information layers including first and second information layers (Land L). The drive includes: an objective lens for converging a light beam; a lens actuator for driving the lens; a photodetector section that receives the beam reflected from the disc and converts it into an electrical signal; and a control section for determining the values of a first group of parameters, which are set to read data from the first layer (L), and those of a second group of parameters, which are set to read data from the second layer (L), during a disc loading process. In performing the disc loading process, the control section determines the values of the first group of parameters, and then determines the values of the second group of parameters based on correlation information, representing correlation between the values of the first and second groups of parameters that were set during a previous disc loading process, and on the values of the first group of parameters that have been just determined during the current disc loading process.

Optical disc and optical disc device

An optical disc apparatus according to the present invention includes a disc type recognizing section for determining whether the optical disc loaded is a first type, of which the number of information storage layers is less than a setting T (where T is an integer that is greater than two), or a second type, of which the number of information storage layers is equal to or greater than the setting T. Depending on whether the optical disc loaded has turned out to be the first type or the second type, the apparatus determines the read/write preprocessing (such as whether a fingerprint detection process needs to be performed or not).

Optical disc apparatus

After an optical disk drive according to the present invention has been loaded with an optical disk and before the operation of recognizing the type of the given disk is finished, the drive presumes one of multiple types of candidate optical disks, from/on which data is readable and writable using a light beam with the shortest wavelength among the candidate disks, to be the disk being driven by the motor now and gets the beam for the presumed type of disk radiated from a light source (Step (A)). Next, the drive gets the disk spun at a rotational velocity that realizes a linear velocity equal to or higher than a standardized normal velocity when data is read from the presumed type of disk (Step (B)). Thereafter, the drive starts a focus control in a situation where the spot of the beam being formed on the disk is moving on the disk at the linear velocity equal to or higher than the normal velocity (Step (C)). And then the drive performs the operation of recognizing the type of the disk by the light beam reflected from the disk under the focus control (Step (D)).

An object of this invention is to measure the tilt quantity of, and perform a tilt control on, an optical disc accurately without depending on the rotation control method. An optical disc drive includes: a motor for rotating an optical disc; an optical system for irradiating the optical disc with a light beam; a moving mechanism for moving the optical system along the radius of the optical disc; a focus control section for controlling movement of the optical system perpendicularly to the optical disc based on drive values, thereby focusing the light beam onto a storage layer of the optical disc; and a tilt control section for measuring the tilt quantities of the storage layer at multiple different radial locations on the optical disc based on drive values for the respective radial locations when the focus control section focuses the light beam there. When the tilt control section measures the tilt quantities, the motor keeps the rotational frequency of the optical disc constant and the tilt control section uses the drive values obtained at the respective radial locations.
