  • Patent number: 10229715
    Abstract: Techniques are disclosed for producing high quality losslessly compressed audio tracks based on conversations between participants remote from one another, such as conversations that occur during a telephonic interview or online conference, or other conversations that take place over a network between two or more participants. In an embodiment, each participant's device includes an audio chat client configured to record that participant's audio contribution to the conversation and store a non-compressed version of the contribution locally. A first version of the captured audio is generated with lossy compression and pushed in real time to a cloud-based service, for purposes of the live conversation. A second version of the captured audio for subsequent playback is generated and stored with lossless compression and is pushed asynchronously to the service. The service is configured to automatically provide a multitrack project with high quality audio tracks from each participant.

  • Patent number: 9575885
    Abstract: A data storage apparatus has a transmission interface, a nonvolatile memory and a controller. The controller records a non-completed flag. When the controller starts a card opening process, the nonvolatile memory is configured under card opening, and the non-completed flag is set non-completed status. When the controller receives a format command form the transmission interface, the nonvolatile memory is formatted and the non-completed flag is set as completed status. When the controller receives a write command, the write data are scrambled before being written to the nonvolatile memory. When in non-completed status, when the controller receives a read command from the transmission interface, no matter whether the data corresponding to the requested address are scrambled, the data are descrambled and descrambled are provided via the transmission interface.

    Abstract: The invention relates to a record carrier of a disc-like optically inscribable type, having a preformed track in which an auxiliary signal comprising a sequence of codes is recorded by means of a preformed track modulation. The codes comprise a sequence of address codes (AC) specifying the addresses of the track portions in which said address codes (AC) are recorded and special codes (SC). The special codes (SC) can be distinguished from said address codes (AC) and specify control data for controlling a recording by a recording device. The sequence can be obtained by replacing in a sequence of address codes (AC) with consecutive address values a plurality of said address by special codes (SC). The periodic pattern of address codes and special codes has a predetermined positional relationship with respect to a predetermined reference address. Such as for example a positional shift with respect to the start of a Lead-in area.

  • Patent number: 8335145
    Abstract: A method of generating a memory disc in an optical disc drive is provided. A request for a change of an optical disc inserted in the optical disc drive into a memory disc is confirmed by detecting if a button included in the optical disc drive is operated. When the request is confirmed, the format of the optical disc may be changed. When an eject button is pushed in a predetermined pattern, for example, when the eject button is pushed for longer than a first reference time or pushed more than twice within a second reference time, the optical disc is initialized into a blank disc, file system data corresponding to the memory disc is recorded in a specific region of the blank disc according to ISO image generating program stored in a non-volatile memory included in the optical disc drive, and the blank disc is formatted.

  • Patent number: 8325576
    Abstract: A configuration for reading out disc management information easily without errors from a disc in which recording is conducted with data recording densities of a plurality of kinds. An optical disc includes a plurality of data recording areas in which information is recorded with data recording densities which are different from each other. Information of the data recording densities in the data recording areas is recorded in a management information recording area (a BCA area or a PIC area) by using a unique format which does not depend upon the data recording densities of the data recording areas. The divided data recording areas are disposed in the same plane of the disc, or disposed over a plurality of recording layers.

  • Patent number: 8325578
    Abstract: For a disc on which recording is to be performed at a plurality of recording densities, a technique for easily reading out disc management information without an error is disclosed. An optical disc (1) includes a plurality of data recording areas (103,104) for recording information at data recording densities different from each other. Information regarding the data recording densities of the data recording areas (103,104) is recorded in a management information recording area (BCA area (101) or PIC area (102)) in a specific format that does not depend on the data recording densities of the data recording areas (103,104). Each data recording area is divided to be arranged on the same surface of the disc, or is divided and arranged on a plurality of recording layers.

  • Patent number: 8320225
    Abstract: A ROM disk having a block data format provided with linking areas as with a rewritable disk. Main data recorded in a main data area and linking data recorded in a linking area in each block are scrambled by identical scrambling data. The scrambling data is generated by a random sequence using address information of the block as an initial value.

  • Patent number: 8305856
    Abstract: To record specific information to a disk-shaped record medium and reproduce the recorded specific information without any influence on the error correction capability. Copy protection information (CPID) having an error correction code appended thereto, shuffled and otherwise treated is sent as a CPID bit block to an EDC rewrite circuit (14). The EDC rewrite circuit (14) rewrites an error detection code appended to user data in each sector in accordance with bit information in the CPID bit block. Thereafter, the data in each sector is scrambled, and an ECC block including a plurality of sectors is modulated with an error correction code and sync signal appended thereto. The modulated signal is recorded in a reserve area of a lead-in area of the disk-shaped record medium. During reproduction, CPID is restored based on the result of error detection of each sector.

  • Patent number: 8300516
    Abstract: An information recording medium that can be rapidly finalized, and a recording/reproducing apparatus and method using the same are provided. In the information recording medium, a prepit is pre-formed in a finalization area. Since the portion that has to be filled with data in finalizing the information recording medium is previously formed as the prepits series in manufacturing the information recording medium, the time necessary to finalize the information recording medium can be shortened, thereby achieving the rapid finalization of the medium.

  • Patent number: 8300505
    Abstract: Method and apparatus for writing repeating patterns of features to a substrate, such as a data storage medium. In accordance with some embodiments, a multi-dimensional pattern of discrete features of different sizes to be written to a substrate is divided into a plurality of contiguous regions. A unique set of compensation values is assigned to each region. A write beam of a write system is used to write the features to the substrate responsive to said unique sets of compensation values so that all of the features having a common size in at least one region are written using the same compensation values from the associated set.
