摘要： An apparatus generates outgoing data (OD) to be provided on an optical disk (1) in a burst cutting area (2). The burst cutting area (2) further comprises markings (3) which cause a marking frequency spectrum (MFS) when reading out the burst cutting area (2). The apparatus comprises a channel coder (4) which receives processed data (PD) and supplies the outgoing data (OD) having an outgoing data frequency spectrum (DFS) with suppressed DC-content. The apparatus further comprises a data processing device (5) which generates the processed data (PD) to obtain an outgoing frequency spectrum (DFS) wherein a frequency component causing interference with a low frequent component of the markings (3) is suppressed or not present.

摘要： The present invention relates to an information reproducing method for reproducing information recorded on an information recording carrier with several information layers by radiating light onto the carrier being e.g. an optical disc. The method comprises the step of 1) focusing the light at a first information layer or a second information layer, where the first layer and the second layer are adjacently positioned in the information recording carrier, 2) performing radial tracking on the reflected light from the information recording carrier, and 3) assessing form the radial tracking if the light is focussed on a clockwise or a counter-clockwise oriented spiral relative to the focussed light. In a particular embodiment, the assessment of whether the light is focussed on a clockwise or a counter-clockwise oriented spiral relative the light is utilized for indicating the identity of the layer on which the light is focussed. The invention also relates to an optical apparatus for implementing the method of the invention.

摘要： A method and system for obtaining focus optimization in an optical disc system is disclosed. The focus offset of a recording unit is set to a first of a plurality of predetermined values. A HF quality value is measured and stored for the selected focus offset value of the recording unit. The focus offset is then set to a best-known focus offset value. Tracks on the optical media being read are then jumped. The above steps are then repeated for each of the plurality of predetermined focus offset values. The optimal focus setting is then determined from the stored HF quality measurements.

摘要： A method of determining a maximum allowable read power for a drive- record carrier combination is described. The method finds a forward-sense setpoint value to control a light power control loop, by reading data from the record carrier at which degradation of the data occurs. This technique is useful for all optical storage devices such as CD, DVD and Blu-ray players and recorders.
