Title:
情報記録方法
Document Type and Number:
Japanese Patent JP4066289
Kind Code:
B2
Abstract:
An information recording method, in which when new digital information is employed to update a part of old digital information that has been divided into ECC blocks and stored on an information recording medium, the latest update position for the old digital information that is to be updated is detected based on the volume of the data of the new digital information. A predetermined volume for the old digital information that has been stored sequentially following the latest update position detected is read, and then, at least a part of the old digital information that has been read is recorded after the new digital information is recorded, so that the destruction of data that should not be rewritten can be prevented at the portion whereat the old digital information is coupled with the new digital information. As a result, the deterioration of the error correction capability for the coupled portion can be reduced.
