摘要

An information recording or reproduction apparatus and method in which a transport packet for padding is not inserted and a limited recording space is used effectively when performing data editing to delete a mid-stream of the moving picture file consisting of an MPEG transport stream and connect the remaining portions. A data portion preceding the deleted portion, a data portion immediately after the deleted potion, and the remaining data portion are recorded as three independent data files and information on the sequence between these data files is recorded together as a management file.
