Abstract
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.
Claims5
A recording medium, in which data is recorded, the data including a digital stream where video information has been encoded,
- wherein 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,
- wherein 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,
- wherein the digital stream is not continuously recorded spanning a boundary between the first recording region and the second recording region,
- and wherein the data file is permitted to be continuously recorded spanning the boundary.
A playback device comprising:
- a reading unit that reads data recorded in a recording medium;
- and
- a playback unit that plays the data that has been read,
- wherein recorded in the recording medium is data including a digital stream where video information has been encoded,
- wherein 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,
- wherein 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,
- wherein the digital stream is not continuously recorded spanning a boundary between the first recording region and the second recording region,
- wherein the data file is permitted to be continuously recorded spanning the boundary,
- and wherein the reading unit reads the digital stream without changing the read rate.
A playback method comprising:
- reading data recorded in a recording medium;
- and
- playing the data that has been read,
- wherein recorded in the recording medium is data including a digital stream where video information has been encoded,
- wherein 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,
- wherein 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,
- wherein the digital stream is not continuously recorded spanning a boundary between the first recording region and the second recording region,
- wherein the data file is permitted to be continuously recorded spanning the boundary,
- and wherein, in the reading, the digital stream is read without changing the read rate.
