Abstract:
1. A data recording method, comprising the steps of: receiving a variable bit-rate data stream encoded in MPEG format; temporarily storing said received variable bit-rate data stream into a buffer memory; detecting a continuous recordable area having a size of at least a predetermined length on a recording medium; said predetermined length being determined on the basis of the length of time for which said variable bit-rate data can be reproduced at a maximum bit-rate without an interruption; and recording said received variable bit-rate data in the continuous recordable area, in which the recording step includes detecting the length of a remaining portion of the next part of said received variable bit-rate data that was not recorded, and if said detected 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.
