Method for copying, recording, and editing data onto disk recording media, and disk recording apparatus

Abstract

A method for copying data in disk recording media, and disk recording apparatus. At copying data recorded in a disk to another disk, occurrence of seek at the copy source is eliminated or suppressed below a specified value during reading data to reduce read time. At the target disk, data is rearranged according to video scenes or files, or file control information is rewritten to maintain the data structure of the copy source.
