摘要： A verify operation is the one that is carried out to further improve reliability of recorded data. Because recording and reproduction are made repeatedly, however, the same time is consumed for reproduction even if recording is made at a double-speed, for example, and recording is substantially equal to recording at a normal recording speed. The verify operation is effective for further improving reliability but reduces the substantial recording speed to a half. To improve recording performance by automatically turning ON and OFF the verify operation in accordance with disks, medium information called “media ID” unique to a disk is acquired in a read-in area of the optical disk. The existence/absence of the verify operation is determined on the basis of a matrix table of an existence/absence of the verify operation corresponding on the 1:1 basis to each media ID provided in advance to an optical disk drive.

摘要： A method for recording/reproducing data to/from a medium by which a table is formed for assigning physical addresses of spare areas of the medium to make the physical addresses be continuous with the last address of logical addresses of a user data recording area, and recording/reproducing is performed by using the table. The physical address of an unused spare area is assigned to make the physical address be continuous with the last address of the logical addresses of the user data recording area. It is therefore possible to use the unused spare area as the user data recording area and to effectively utilize the unused spare area.
