Abstract

An information recording method of recording additional or modified data with an information recording and reproducing apparatus on a rewritable information recording medium on which previous data, a previous file descriptor group, a previous volume descriptor group, and a previous anchor are recorded, is provided. The method comprising the steps of recording the additional or modified data on the rewritable information recording medium; recording an additional file descriptor group on the rewritable information recording medium; recording an additional volume descriptor group on the rewritable information recording medium; and updating the previous anchor recorded on the rewritable information recording medium. The additional / modified data recording step, the additional file descriptor group recording step, the additional volume descriptor group recording step, and the anchor updating step are performed in a consecutive manner.

Description

technical field [0001] The present invention relates to an information recording method and an information recording and reproducing device for recording information on an information recording medium. The above-mentioned information recording medium refers to an optical disc (CD, DVD, etc.), a magneto-optical disc, a magnetic disc (hard disc, floppy disc, LS120, ZIP, etc.), A re-recordable information recording medium mainly used in computer systems such as a memory card (erasable and rewritable ROM / RAM, etc.). Background technique [0002] Methods and systems for reading rewritable optical discs using existing operating systems are known. For example, Japanese Patent Publication No. 06-064521 describes a method and system for managing a re-recordable optical disc, which improves the physical design of the address conversion mechanism, so that the re-recordable disc can be read by the operating system. [0003] In an information recording and reproducin...
