Abstract: A method for backing up and restoring a disc management information is disclosed. Firstly, a specified optical disc is loaded into an optical disc drive. After a servo calibration process is performed, the latest update of the disc management information is read from a specified optical disc. If the latest update of the disc management information is read successfully, the optical disc drive enters a normal working state.

Consequently, the optical disc drive enters the normal working state. While the normal working state of the optical disc drive is terminated, the latest update of the disc management information is transmitted to the processing circuit and recorded into the storage device.

Abstract: With quantization index modulation QIM it is possible to achieve a very high data rate, and the capacity of the watermark transmission is mostly independent of the characteristics of the original audio signal, but the audio quality suffers from degradation with each watermark embedding-and-removal step. In order to avoid degradation of the audio quality, the inventive audio signal watermarking uses specific quantizer curves in time domain and in particular in frequency domain for embedding the watermark message into the audio signal, whereby the processing is almost perfectly reversible. Furthermore, it has embedded a power constraint in order to guarantee that the modifications of the audio signal due to the watermark embedding are inaudible.

Abstract: The present technology relates to a recording control apparatus, a recording control method, a drive controlling controller, a drive controlling method, a recording medium, and a program capable of reading information more reliably.

As described above, since DMSs as management information are recorded in the different areas of the optical disc, even if DMS cannot be read from one area, DMS can be read from the other area. The present technology is applicable to a recording and reproducing apparatus.

Abstract: A mechanism is provided that aggregates data in a way that permits data to be deleted efficiently, while minimizing the overhead necessary to support bulk deletion of data. A request is received for automatic deletion of segments in a container and a waterline is determined for the container. A determination is made if at least one segment in the container falls below the waterline. Finally, in response to one segment falling below the waterline, the segment from the container is deleted. Each object has an associated creation time, initial retention value, and retention decay curve (also known as a retention curve). At any point, based on these values and the current time, the object's current retention value may be computed. The container system continually maintains a time-varying waterline: at any point, objects with a retention value below the waterline may be deleted.
