摘要： A method of recording digital information signals on a removable rewritable disc like recording medium, the method including recording user data on a logical area of the disc and, prior to removal of the disc out of a recording/reproducing apparatus, finalizing the disc with a lead-in and lead-out area comprising predefined medium format data. A general purpose area within the logical area for other use than recording of user data, is being reserved. Such a use may be, for example, defect management. Further, the method involves interrupting recording a lead-in area or a lead-out area at predefined splice points whenever a request for user data is made.

摘要： A recording apparatus for recording data on a rewritable optical recording medium has been proposed. The apparatus comprises input means (27) for rewriting the data, recording means (21, 22, 25, 28, 29) for recording the data reading means (21, 22, 25, 30) for reading the recorded data, error correction means (30) for finding and correcting errors in the recorded data read and control means (20) for controlling the recording and reading of the data. The recording apparatus is capable of performing fast and efficient examination of formatted recording medium in order to adapt a data recording strategy, so as to increase the efficiency of writing operations.

摘要： Arrangement for carrying out a concealment on an information signal, the information signal including subsequent signal blocks (padding sequence), each signal block including a sequence of alternate first frames and second frames of different lengths, expressed in numbers of bits, the number of first frames and second frames in a signal block being N1 and N1-1 respectively. The last frame in a signal block and the first frame in a subsequent signal block are a first frame. The arrangement includes an input terminal for receiving the information signal, a concealment unit having an input coupled to the input terminal and an output coupled to an output terminal for supplying the concealed information signal. The concealment unit is adapted to conceal the information in response to a concealment control signal. More specifically, the concealment unit is adapted to conceal a number of M subsequent frames, M being an odd integer smaller than 2.N1-1. The concealment unit includes a memory for storing M+1 subsequent frames directly preceding the M subsequent frames to be concealed. For various situations, concealment is realized by appropriately generating frames for replacing the frames to be concealed, using the frames stored in the memory.
