摘要： In recording and reproducing devices that use angular-multiplexing holography, accessing a recorded hologram of interest had taken time because after positioning at the vicinity of the hologram, it had been necessary to carry out fine adjustment of the position while checking the signal quality of the hologram. The optical information recording and reproducing device according to the present invention uses angular-multiplexing to record interference patterns formed from a signal beam and a reference beam onto an optical information recording medium as page data and reproduces information from the optical information recording medium, said optical information recording and reproducing unit being provided with: a light-source unit that outputs light; an optical splitting unit that splits the light into a reference beam and a signal beam; an angle controlling unit that controls the angle for the direction of angle multiplexing at which the reference beam enters the optical information recording medium; an optical detecting unit that detects a reproduced image that is reproduced by using the reference light; and a position control unit that controls the position relationship between the reference beam and the optical information recording medium. The device treats a set of page data as a book, and during recording, at least a portion of the page data in adjacent books is recorded while the entrance angle for the direction of angular-multiplexing for the reference light is shifted by means of the angle controlling unit. During reproduction, at least a portion of the light amount of a reproduced image is detected by using the optical detecting unit, and the position of the book is detected on the basis of information about the detected light amount.

摘要： An optical disc device and a recording method is provided in which information can be additionally recorded on an optical disc, which has a servo layer and recording layers separately formed, by accurately correcting a relative angle between a light beam and the optical disc used in the previous recording without providing an area where recording is not performed while maintaining the stability of tracking servo. The above subject can be solved by studying with high accuracy the relative angle between the optical disc and the optical axis used in the previous recording by applying a radial tilt servo according to a signal from the recording layers with the tracking servo applied by the servo layer. Further, the additional recording can be performed stably by fixing the radial tilt at the previously studied angle when the recording is performed.

摘要： The purpose of the present invention is to provide an optical information recording/reproducing device and the like that can suppress a decrease in a recording speed even where an optical information recording medium including multiple layers has eccentricity. The optical information recording/reproducing device records information, by treating a predefined area in a second layer corresponding to a position of a first layer at which a defect is detected, as a defect area. The optical information recording/reproducing device reproduces information, by treating a predefined area in the second layer corresponding to a position of the first layer at which a defect is registered, as a defect area. The radial distance of the defect area is preferably greater than a bonding error between the first and second layers.
