Abstract
The present invention provides a thin optical disc drive whose impact resistance performance is improved. An under coveris provided with a collision evasion holeat a position corresponding to an end of an optical head housing. Moreover, a bottom coveris provided with an impact force buffering memberat a position corresponding to the collision evasion hole. When an impact force acts on an optical disc drive, the impact force to the optical head housingis buffered by the structure. Consequently, it is possible to prevent the optical headfrom being damaged, and it is possible to improve the reliability of the optical disc drive
