setting parameters to correspond to DVD− parameters that enable reading of the general wobble signal from the DVD. Description
This application claims the priority benefits of U.S. provisional application titled �NEW METHOD OF IDENTIFYING ROM/R/RW TYPE OF DVD DISC (USING TE SIGNAL, RECD SIGNAL AND RFLVL SIGNAL)� filed on May 25, 2004, Ser. No. 60/574,665. All disclosure of this application is incorporated herein by reference. This application also claims the priority benefit of Taiwan applications serial no. 93130202, filed on Oct. 6, 2004, serial no. 93127819, filed on Sep. 15, 2004. All disclosure of these Taiwan applications is incorporated herein by reference.
Digital versatile disc (DVD) is now a very popular optical storage medium. Aside from the read-only DVD-ROM (the �ROM� part refers to a read-only memory), DVD that can be used for recording data is available. DVD that can be used for recording data can be further classified into DVD− and DVD+ according to specifications. At present most DVD players are compatible to a number of specifications. Therefore, the technique of determining the type of a DVD is quite important.
