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 spoke detecting device, a spindle motor PCB and an insulating pad. The spoke detecting device is used for detecting spoke patterns on the lightscribe disc. The spindle motor PCB is communicated with the spoke detecting device through a flexible cable. The insulating pad is coupled with the spindle motor PCB for supporting the spoke detecting device 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 spoke detecting device for detecting spoke patterns on the lightscribe disc;   a spindle motor PCB communicated with the spoke detecting device through a flexible cable; and   an insulating pad coupled with the spindle motor PCB for supporting the spoke detecting device 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 further 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 1  wherein the insulating pad is attached on the spindle motor PCB by screwing or using adhesive. 
     
     
         5 . The optical disc drive according to  claim 1  wherein the flexible cable is a flexible flat cable. 
     
     
         6 . The optical disc drive according to  claim 1  wherein the insulating pad is made of plastic material.
