Description

ABSTRACT:
A disc in which a digital versatile disc (DVD) application is recorded in a physical layer of the disc, a recording/reproducing apparatus, and a recording/reproducing method are provided. In the disc, a lead-in area, a lead-out area and a user area, each having a compact disc read only memory (CD-ROM) format, are distinguished on the physical layer of the disc and a digital versatile disc (DVD) application, according to a predetermined file system, is recorded in the user area. Therefore, a low-priced disc can be used for a music video or a presentation which requires only a shorttime to reproduce since the DVD application can be recorded on and reproduced from the disc to obtain multiple functions having high image quality and high sound quality.
