Optical disc medium, and apparatus and method for recording data on the same |
摘要 |
An optical disc medium includes a system area and a data area. The system area includes a recording operation test area to which a trial recording operation is carried out to determine an optimal record condition when data is recorded in the data area; a record control data area where data necessary to record user data on the data area is recorded; and a user data lead-in area necessary to reproduce the user data from the optical disc medium. Dummy data are recorded to a portion of the record control data area on a side of the user data lead-in area to prevent a track-out when the data area is accessed.
