With an ink jet head having for each color two parallel columns of nozzles arranged shifted by one-half the pitch, odd-numbered rasters and even-numbered rasters are printed by the two nozzle columns. The registration between the odd- and even-numbered rasters is secured during the printing to produce a high quality image. The ink ejection timing between the two raster groups is shifted by a predetermined interval to form adjustment patterns; the adjustment patterns are checked and, according to the check result, an adjustment value for the ink ejection timing between the two ink nozzle columns is entered, and the entered adjustment value is stored to be reflected on the actual printing operation. To facilitate the adjustment pattern check, the adjustment patterns have a dot distribution with a blue noise characteristic at a resolution at which the printing apparatus can print.

Management information for video data and audio data that are created after their recording is started until it is stopped and that are recorded as a stream file on a record medium is more securely stored. When their recording is started, EP entry information contained in management information of the stream file is created. Whenever EP entry information is created, it is written to a nonvolatile memory. After their recording is stopped, fixed value information and so forth that are contained in the management information are created and written to the nonvolatile memory. According to a disc eject operation, the management information written to the nonvolatile memory is written to the disc and the contents stored in the nonvolatile memory are cleared. Likewise, when power is turned off without the eject operation, information stored in the nonvolatile memory is written to the disc. Since the management information is stored in the nonvolatile memory, even if power is unexpectedly turned off, the management information will not be lost.

To allow AV data created after the start of recording until the end of recoding to be easily continuously recorded and reproduced for a long time as a file. A stream of which AV data have been multiplexed is recorded to a file in the unit of a packet. When the file size exceeds 2 GB with the next packet that is recorded, record control is performed such that the time of the last end of audio data of the current file matches the time of the beginning of audio data of the next file to which the stream is recorded, the current file is closed, and seamless connection that denotes that the closed file and the next file to which the stream is recorded are connected such that audio data do not overlap is set. A file is newly created and the stream is continuously recorded thereto. The recording of the file is stopped according to a stop operation. When the recording is performed for a long time, a file is automatically divided. Upon reproducing, files in which the stream has been recorded for a long time can be continuously reproduced without causing the user to recognize the division of the file.

A method for initializing a recording medium on which data is recorded in compliance with the AVCHD standard is proposed. Under a root directory of partitions, an ICB and FIDs for each directory contained in a directory structure defined by the AVCHD standard are recorded with consideration of information on child directories. Thereafter, an SBD and a metadata bitmap file are recorded in a partition and also, an LVIS is recorded on the basis of information, such as the number of sectors used as a result of recording the ICBs and the FIDs of all the directories and the total number of directories.

Data recording device, data recording method, and computer program

Provided are a device and a method for identifying whether or not an information recording medium is a pre-formatted disc, and an information recording medium as a pre-formatted disc. In an information processing device that executes recording of data onto a disc, such as a video camera, a process of identifying which one of the following discs a loaded disc is, that is, whether the loaded disc is (a) an unrecorded blank disc, (b) a pre-formatted disc to which a padding process has been applied, or (c) an already-recorded disc, is executed as a process of recognizing the loaded disc. With this configuration, a padding process that needs to be executed during a formatting process or finalizing process in conventional devices becomes unnecessary, thus enabling quick processing without making the user wait during the start of recording or finalizing process.

By using an ink jet head, which has for each color two parallel columns of nozzles arranged side by side in the main scan direction and shifted from each other by one-half the pitch at which the nozzles are arranged in each column, odd-numbered rasters and even-numbered rasters making up an image are printed by the two nozzle columns. The registration between the odd- and even-numbered rasters is secured during the printing to produce an image with high print quality. For that purpose, the ink ejection timing between the two raster groups is shifted by a predetermined interval to form a plurality of adjustment patterns; the adjustment patterns printed are checked and, according to the check result, an adjustment value for the ink ejection timing between the two ink nozzle columns is entered, and the entered adjustment value is stored to be reflected on the actual printing operation. To facilitate the adjustment pattern check, the plurality of adjustment patterns have a dot distribution with a blue noise characteristic at a resolution at which the printing apparatus can print.

Recording of video data is enabled by a management structure of a clip which is compatible with a BD-ROM standard. In accordance with the recording starting operation, the recording of a stream in which the video data and audio data have time-divisionally been multiplexed on a packet unit basis onto a recording medium is started. In accordance with the recording stopping operation, the stream stored in a buffer is written as a stream file onto the recording medium and a clip information file corresponding to the stream file is formed. A play item showing the whole clip information file is formed and added to the existing play list on the recording medium. A mark is stamped to the play list at time corresponding to an IN point of the play item. Subsequently, the play item which is formed in association with the recording start and stop is similarly further added to the existing play list and the mark is further stamped at the time corresponding to the IN point.
