Host data to be written to a recording medium is categorized as one of sequential data or random data. The sequential data is written to a first track width on the recording medium. The random data is written to a second track width on the recording medium, the second track width being larger than the first track width.

A magnetic tape for use in a tape drive includes a plurality of tracks and a plurality of media defect characteristics. The plurality of tracks are laid out along a length of the magnetic tape, each of the plurality of tracks being configured to receive data that is organized into a plurality of fixed-size subdata sets each including a plurality of codeword interleaves. The data is laid out on the plurality of tracks in accordance with a tape layout allocation strategy as determined by a tape layout module. The tape layout module includes a tape layout optimization system that receives information on the plurality of media defect characteristics, the tape layout optimization system determining the tape layout allocation strategy based at least in part on at least one of the plurality of media defect characteristics; and the tape layout optimization system determining the tape layout allocation strategy further based on distance spectra between pairs of the plurality of codeword interleaves.

A tape layout module for determining a tape layout allocation strategy for laying out data on tape, the data being organized into a plurality of fixed-size subdata sets with each of the plurality of subdata sets including a plurality of codeword interleaves, the tape including a plurality of media defect characteristics, includes a tape layout optimization system including a processor that receives information on the plurality of media defect characteristics. The tape layout optimization system determines the tape layout allocation strategy based at least in part on at least one of the plurality of media defect characteristics. Additionally, the tape layout optimization system can determine the tape layout allocation strategy further based on distance spectra between pairs of the plurality of codeword interleaves. Further, the tape layout optimization system can determine the tape layout allocation strategy by selectively utilizing at least one tape layout parameter.

A recording medium records data including a digital stream where video information has been encoded. A recording region of the recording medium has a first recording region where reading is performed at a first read rate, and a second recording region where reading is performed at a second read rate that is faster than the first read rate. The data is classified into digital stream data having a real-time attribute and a data file having a non-real-time attribute in a file system of the data. The digital stream is not continuously recorded spanning a boundary between the first recording region and the second recording region. The data file is permitted to be continuously recorded spanning the boundary.

An information processing device includes: a data processing unit which executes a reproduction process of recorded data of a disc, in which the data processing unit reads disc type information that is recorded on the disc, and ascertains a recorded data configuration of the disc based on the disc type information that is read, and executes data reading-out and reproduction processes according to a reading-out rate corresponding to the ascertained recorded data configuration.

Data including a digital stream file obtained by encoding video information is recorded in a recording medium. A recording region of the recording medium has a first recording region where reading is performed at a first read rate, and a second recording region where reading is performed at a second read rate that is faster than the first read rate. The data includes a digital stream file having real-time attributes and a data file having non-real-time attributes. The data file to be read in during playback of the digital stream file is recorded in, of the first recording region and the second recording region, the same recording region where the digital stream file being played is recorded.

A tape layout module for determining a tape layout allocation strategy for laying out data on tape, the data being organized into a plurality of fixed-size subdata sets with each of the plurality of subdata sets including a plurality of codeword interleaves, the tape including a plurality of media defect characteristics, includes a tape layout optimization system including a processor that receives information on the plurality of media defect characteristics. The tape layout optimization system determines the tape layout allocation strategy based at least in part on at least one of the plurality of media defect characteristics. Additionally, the tape layout optimization system can determine the tape layout allocation strategy further based on distance spectra between pairs of the plurality of codeword interleaves. Further, the tape layout optimization system can determine the tape layout allocation strategy by selectively utilizing at least one tape layout parameter.

A playback device is provided that includes a readout unit that reads out data recorded in a recording medium and a playback unit. Data including a digital stream file obtained by encoding video information is recorded in the recording medium. A recording region of the recording medium has a first recording region where reading is performed at a first read rate, and a second recording region where reading is performed at a second read rate that is faster than the first read rate. In a file system, the data is classified into the digital stream file having real-time attributes and a data file having non-real-time attributes, wherein the data file read in during playback of the digital stream file is recorded in the same recording region where the digital stream file being played is recorded. The readout unit reads out the data without changing the first or second read rate.

An article of manufacture includes a machine-readable medium that stores a multimedia content file in a first format and multiple program sets. Each program set is a version of software that, when executed by a respective electronic system, produces the multimedia content file in a second format for use in the respective electronic system. A first program set is compatible with a first operating system executed by a first electronic system and a second program set is compatible with a second operating system executed by a second electronic system. The second operating system is distinct from the first operating system.

A playback device is provided that includes a readout unit that reads out data recorded in a recording medium and a playback unit. Data including a digital stream file obtained by encoding video information is recorded in the recording medium. A recording region of the recording medium has a first recording region where reading is performed at a first read rate, and a second recording region where reading is performed at a second read rate that is faster than the first read rate. In a file system, the data is classified into the digital stream file having real-time attributes and a data file having non-real-time attributes, wherein the data file read in during playback of the digital stream file is recorded in the same recording region where the digital stream file being played is recorded. The readout unit reads out the data without changing the first or second read rate.
