Beschreibung
Zusammenfassung:	PURPOSE: A method of decreasing vibration for improving performance of a CD-ROM drive is provided to reduce vibration by reducing weight of a spindle motor and length of a shaft, as well as minimizing effect of vibration by upwardly protruding a portion supporting the spindle motor of a deck to compensate for a difference in structure between the present invention and the existing product due to the reduced length of the spindle motor and by reinforming the structure with a rib to reinforce the structural strength. CONSTITUTION: A spindle motor is embedded in a CD-ROM drive. A length of the spindle motor is reduced. A portion on which a spindle motor(130) is disposed is protruded. A reinforcing material(90) is interposed between the protruded portion and other unprotruded portion. The present invention has an advantage of increasing speed performance when being compared with the existing products by reducing vibration through the structural improvement.
