Abstract
A method and apparatus for copying/moving data on an optical recording medium is disclosed, in which data moves or copies in one disc using a memory and data transmission to a host is omitted when the data moves or copies in one optical disc. To this end, identification information is assigned to a reserved area of read/write commands generated from the host, thereby displaying data movement status or data copying status. Thus, it is possible to reduce the data transmission time when the data moves or copies in one disc. Furthermore, even if the read/write commands in one file or the whole data to move or copy occur several times, the data transmission time such as the data movement time and the data copying time can be reduced by reducing the number of physical access times of the optical disc for the data reading/writing operation.
