  • Publication number: 20090324204
    Abstract: This invention provides an information processing method and apparatus, which can set all extent sizes of data divisionally recorded on a disk to be equal to or larger than the minimum recording unit, and can guarantee continuous reproduction of the divisionally recorded data. Of data divisionally recorded on a recording medium (5), data which corresponds to an end portion of that data and cannot be recorded as a recording area equal to or larger than a minimum recording unit specified in the recording medium (5) due to the presence of a recording area (6) of another data, that has already been recorded on the recording medium (5), is re-recorded on a recording area equal to or larger than the minimum recording unit. At this time, new data is generated by combining data less than the minimum recording unit, and data recorded in another recording area, and the new data is re-recorded on a new recording area.
