Abstract:
1. A data recording apparatus for recording data onto a recording medium to be reproduced by a reproduction device, comprising: inserting means for inserting into data to be recorded variable bit-rate data having a size smaller than a predetermined length; wherein the variable bit-rate data is encoded in MPEG format, and said predetermined length being determined on the basis of the length of time for which the variable bit-rate data can be reproduced at a maximum bit-rate without an interruption; combining means for combining the inserted variable bit-rate data with recorded data adjacent to the inserted variable bit-rate data to form a data unit of at least said predetermined length; and recording means for recording the data unit in a continuous recordable area on the recording medium, in which the recording means includes means for detecting the length of a remaining portion of the next pad of the data to be recorded, that was not recorded, and if said remaining portion has a length less than said predetermined length, then locating another non-recorded area on said recording medium having a size of at least said predetermined length.
