20090080304INFORMATION RECORDING MEDIUM, RECORDING AND/OR REPRODUCING APPARATUS, AND RECORDING AND/OR REPRODUCING METHOD - An information recording medium, recording and/or reproducing apparatuses, and recording and/or reproducing methods which enable effective management of a last data recording address of a data area of the information recording medium. The information recording medium includes a data area for recording user data, temporary recording management information for managing a data recording status of the data area and temporary disc management information for managing the information recording medium, wherein the temporary disc management information includes first information regarding a last recorded location of data in the data area and second information regarding whether the information regarding the last recorded location is consistent with an actual last recorded location of the data area.03-26-2009
20090154901METHOD AND APPARATUS FOR REPRODUCING DATA - A method and apparatus for reproducing data. The method includes downloading data in a local storage; and reproducing the data according to a predetermined reproduction order, wherein when data that is to be reproduced next has not yet been downloaded, the reproducing of the data according to the predetermined reproduction order includes: stopping data reproduction; and when downloading the data that is to be reproduced next is completed, reproducing data from the location where data reproduction stopped.06-18-2009
20100281275METHOD OF RECORDING CONTENT ON DISC, METHOD OF PROVIDING TITLE KEY, APPARATUS FOR RECORDING CONTENT ON DISC, AND CONTENT PROVIDING SERVER - Provided are a method of recording content, a method of providing a title key, an apparatus for recording content, and a content providing server, which can prevent unauthorized users from recording the title key on a plurality of discs. The method of recording content downloaded from a network includes: receiving a title key, which is encrypted with a disc key of a disc on which content is to be recorded in a recording apparatus, from a server; and recording the received title key and the content on the disc.11-04-2010
20100296372RECORDING MEDIUM, METHOD AND APPARATUS FOR REPRODUCING DATA ON THE RECORDING MEDIUM, AND METHOD AND APPARATUS FOR RECORDING DATA ON THE RECORDING MEDIUM - A recording medium on which data is recorded in units of clusters, a method and apparatus for reproducing data on the recording medium, and a method and apparatus for recording data on the recording medium, wherein each of the clusters includes a plurality of address fields, each address field includes 32-bit address unit number (AUN) address information, and the AUN address information includes a reserved area recorded on 4 bits, layer information, recorded on 3 bits, indicating a layer on which data corresponding to the AUN address information is recorded, and location information, recorded on 25 bits, indicating a location of the data corresponding to the AUN address information. In the recording medium of the present invention, a space in which addresses are recorded is expanded, thereby securing an address area in which addresses of data can be recorded in a data structure.11-25-2010
