Lightscribe optical disc drive

Abstract

An optical disc drive for marking a label side of a lightscribe disc is provided. The optical disc drive includes a metallic plate, a spoke detecting device and a spindle motor PCB. The spoke detecting device is used for detecting spoke patterns on the lightscribe disc. The spindle motor PCB is supported on the metallic plate and having a notch such that a receptacle is defined by sidewalls of the notch and a surface of the metallic plate. The spoke detecting device is received in the receptacle such that the spoke detecting device is separated from the lightscribe disc by a specified gap.

1 . An optical disc drive for marking a label side of a lightscribe disc, the optical disc drive comprising:
 a metallic plate;   a spindle motor PCB supported on the metallic plate and having a notch such that a receptacle is defined by sidewalls of the notch and a surface of the metallic plate; and   a spoke detecting device for detecting spoke patterns on the lightscribe disc, wherein the spoke detecting device is received in the receptacle such that the spoke detecting device is separated from the lightscribe disc by a specified gap.   
     
     
         2 . The optical disc drive according to  claim 1  wherein the spoke detecting device comprises:
 a spoke detector PCB; and 
 a spoke detector mounted on the spoke detector PCB and electrically connected to the spoke detector PCB. 
 
     
     
         3 . The optical disc drive according to  claim 2  wherein the spoke detector is mounted on the spoke detector PCB according to the surface mounted technology. 
     
     
         4 . The optical disc drive according to  claim 2  wherein the spoke detector PCB and the metallic plate have respective screw holes and a fastening element is screwed in the screw holes to fix the spoke detecting device on the metallic plate. 
     
     
         5 . The optical disc drive according to  claim 2  wherein the spoke detector PCB and the metallic plate have complementary retaining structures to be engaged with each other.
