Abstract: Disclosed herein are a recording medium, an apparatus for forming the recording medium, and an apparatus and method for reproducing the recording medium. CPI (Copy Protection-related Information), identification information (CPI_Flag) indicative of recording or non-recording of the CPI, and/or a plurality of contents specific information (CSI) with different formats are recorded in a PIC (Permanent Information & Control data) zone of a high-density optical disc such as a BD-ROM (Blu-ray Disc-ROM). A formatting operation and mastering operation are performed under the condition that control data including the CPI, CPI_Flag and/or CSI is separated from main data. An optical disc device judges whether the optical disc has been illegally copied, with reference to the CPI, CPI_Flag and/or CSI read from the optical disc, and compulsorily stops a data playback operation upon judging that the disc has been illegally copied.

Abstract: In a recordable optical disc including at least one recording layer, writing speed information and per writing speed write strategy information are recorded within disc control information, so that standardized disc control information can be uniformly applied to data recording and reproduction. At least one disc control information is recorded within the management area in per applicable writing speed order, and at least one disc information is recorded within a same writing speed in per recording layer order.

Abstract: A high-density optical disc, a method for encrypting data and recording the encrypted data thereon, and a method for reproducing the encrypted data recorded thereon. Data recorded on a high-density optical disc such as a Blu-ray disc-read only memory (BD-ROM) is recorded in a discontinuous recording format as on a high-density rewritable optical disc such as a Blu-ray disc rewritable (BD-RE). Data can be encrypted and recorded using synchronous data, address unit number (AUN) information or disc radius information recorded in the high-density optical disc. An optical disc apparatus such as a BD-ROM player can maintain reproduction compatibility with the high-density rewritable optical disc such as the BD-RE. A user holding an optical disc apparatus such as a BD-RE recorder, etc. can be prevented from unlawfully copying data recorded on the high-density optical disc and reproducing the copied data.

Abstract: In one embodiment the method includes reading speed information from a specific area of the recording medium. The speed information includes one or more speed flags to indicate whether a corresponding speed is applicable to the recording medium. A first speed flag for a first recording speed lower than a second recording speed is set to be dependent on a second speed flag for the second recording speed. Data is recorded on a main data area of the optical recording medium based on the read speed information.

Abstract: A method for recording data on a recording medium having one or more recording layers. The method includes reading control information having a plurality of control information units for controlling recording/reproducing of data from the recording medium. The control information unit includes an identifier of the recording layer to which the control information unit applies and a recording velocity applicable to the corresponding recording layer. A sequence of the information units is ordered according to the recording velocity and the recording layer identifier.

Abstract: The present invention provides a method of managing a defective area of an optical disc recordable at high speed, recording/reproducing method thereof, and recording/reproducing apparatus thereof, by which an accurate decision of the defective area is provided.
