Abstract
A control apparatus for use with a recordable recording medium, such as a write once compact disc (CD-WO), in accordance with a SCSI-2 interface previously defined for a pre-recorded recording medium, such as a normal CD, automatically sets and updates attribute information needed for recording the CD-WO. When the CD-WO is blank or partially written, track information pages, in addition to a disc information page, are used to manage recording medium attribute information. The disc and track information pages are associated with corresponding disc and track changeability information pages.
