Discrimination method of optical storage medium

Abstract

A discrimination method of an optical storage medium is provided. The method scans a plurality of data recording points, and obtains a channel bit rage according to the scanned data recording points. After obtaining the channel bit rate, the channel bit rate is compared with a predetermined value, and the optical storage medium used for storing the data recording points is discriminated by checking the channel bit rate.

1 . A discrimination method of an optical storage medium, comprising: 
 scanning a plurality of data recording points at IX speed;    obtaining a corresponding channel bit rate according to the scanned data recording points;    comparing the channel bit rate with a predetermined value; and    discriminating a type of the optical storage medium for storing the data recording points according to a comparison result.    
     
     
         2 . The discrimination method of the optical storage medium of  claim 1 , wherein the predetermined value is between 4.3218 Mbps and 26.16 Mbps.  
     
     
         3 . The discrimination method of the optical storage medium of  claim 1 , wherein when the channel bit rate is larger than the predetermined value, the optical storage medium is discriminated as a DVD.  
     
     
         4 . The discrimination method of the optical storage medium of  claim 1 , wherein when the channel bit rate is less than the predetermined value, the optical storage medium is discriminated as a CD.  
     
     
         5 . The discrimination method of the optical storage medium of  claim 1 , wherein if the channel bit rate is essentially equal to 4.3218 Mbps, the optical storage medium is discriminated as a CD, otherwise, the optical storage medium is discriminated as a DVD.  
     
     
         6 . The discrimination method of the optical storage medium of  claim 1 , wherein if the channel bit rate is essentially equal to 26.16 Mbps, the optical storage medium is discriminated as a DVD, otherwise, the optical storage medium is discriminated as a CD.
