Recording and reproducing device for optical disc

Abstract

To provide a recording and reproducing device for an optical disc. There are included a spindle motor for rotating the optical disc, a mechanical chassis for fixing the spindle motor, a fixing member provided on the spindle motor, and a bonding member for fixing the spindle motor to the mechanical chassis by bonding the fixing member to the mechanical chassis in a state in which attitude adjustment and positioning are performed.

1 . A recording and reproducing device for an optical disc, comprising: 
 a spindle motor for rotating the optical disc;    a mechanical chassis for fixing the spindle motor;    a fixing member provided on the spindle motor; and    bonding means for fixing the spindle motor to the mechanical chassis by bonding the fixing member to the mechanical chassis in a state in which attitude adjustment and positioning are performed.    
     
     
         2 . The recording and reproducing device for an optical disc according to  claim 1 , wherein the bonding means is one of adhesive, wax, and welding.  
     
     
         3 . The recording and reproducing device for an optical disc according to  claim 1 , wherein the fixing member protrudes outward from the spindle motor, and the mechanical chassis has a recessed step filled with the fixing member.  
     
     
         4 . The recording and reproducing device for an optical disc according to  claim 1 , further comprising a guard formed in parallel with a shaft center of the spindle motor at a distance from an outer circumference of the spindle motor in a diameter direction.  
     
     
         5 . The recording and reproducing device for an optical disc according to  claim 4 , wherein the guard is formed integrally with the fixing member.  
     
     
         6 . An assembling device for the recording and reproducing device for an optical disc according to any one of  claims 1  to  5 , wherein 
 the optical disc has a track,  
 the spindle motor has a turntable for mounting an optical disc, the turntable having a turntable surface,  
 the recording and reproducing device has an optical pickup for recording and reproducing information on the optical disc, and  
 the assembling device is provided outside the recording and reproducing device, the assembling device comprising means for adjusting inclination of the spindle motor in a track width direction, means for adjusting inclination of the spindle motor in a track tangent direction, and means for adjusting a height of the spindle motor relative to the optical pickup.  
 
     
     
         7 . The assembling device according to  claim 6 , further comprising means for adjusting a position of the spindle motor in a surface direction of the optical disc.
