Abstract:
A resonance removing mechanism installed on a CD-RW drive to remove resonance, the CD-RW drive contains a tray, a read/write head, a CD-RW driving plate and other components, the tray controlled by a motor at the front of a chassis frame through a set of gears and a linking component; the read-write head installed between and sliding on two sliding rods and connecting to the chassis frame through the resonance removing mechanism composed of a first holding-down plate and a second holding-down plate to isolate the vibration between the CD-RW driving plate and the chassis frame, characterized in that:each end of the sliding rods are fixed on the two sides of the frame-shaped space of the first holding-down plate through a sliding rod seat; the CD-RW driving plate is installed at one side of the frame-shaped space of the first holding-down plate; the first holding-down plate connects to the chassis frame through a series of elastic pads on the two end faces at the sides; a series of first elastic pads provide appropriate elasticity between the first holding-down plate and the frame-shaped space and isolate the vibration effectively; the second holding-down plate connects to the first holding-down plate through a series of second elastic pads.
