20080212457 | Scanning Of Multi-Layer Optical Record Carriers - An optical scanning device for scanning a first and a second information layer of an optical record carrier, a scanning method, and an optical record carrier. The device includes at least one radiation source for providing a first radiation beam for scanning the first information layer and a second radiation beam for scanning the second information layer. An objective lens system is arranged to converge the first and second radiation beams on the respective information layers. The device is configured to determine tracking information from only one of said radiation beams, for tracking error compensation. | 09-04-2008 |
20080232208 | High Frequency Central Aperture Tracking - The present invention relates to an optical system for performing radial tracking on an associated optical record carrier. The optical system contains at least one radiation-emitting device capable of emitting at least three beams: a first beam for reading and/or recording information, and at least a second beam and a third beam for tracking. The optical system is adapted for radial tracking of the first spot from a tracking error signal generated based on the high-frequency component of the central-aperture signal of the second and third beams. The tracking error signal may be generated based on a difference signal of a DC-level of the power of the high-frequency components of the central-aperture signal. | 09-25-2008 |
20080239898 | Calibration of Relative Laser Intensities in an Optical Storage System - In conventional one-dimensional optical storage systems, the data is arranged in a linear fashion, and the format is read out by a single spot. A two-dimensional encoded disc is different, because the data is arranged in a two-dimensional manner (bits are on a bit lattice) and the data is read out by multiple spots. It is important to know the relative intensity of the read-out spots, because the intersymbol interference is used in the signal processing of the reflected signals, and the present invention provides a way of calibrating the relative intensities by placing one or more mirror sections ( | 10-02-2008 |
20080314407 | Method of Cleaning an Optical Face of a Refractive Element for a Near Field Optical Scanning Apparatus and a Cleaning Device for Cleaning an Optical Face of a Refractive Element for a Near Field Optical Scanning Apparatus - The invention provides a method and a device for cleaning of the optical face of a refractive element for a near field optical scanning apparatus. A magnetically susceptible cleaning material is used to facilitate effective cleaning of the refractive element without damage to the element. The method according to the invention can be combined with known cleaning methods if desired. | 12-25-2008 |
