Slot-in optical disk drive

The present invention relates to an optical disk drive, and particularly a slot-in optical disk drive, which is to chisel a plurality of mutually corresponding slot holes and slot rails on the shell and a slider configured therein, so as to suitably assemble a disk-in rocker arm, a disk-out rocker arm, a core base, a holding rod, and a driving block thereon, furthermore, limit the horizontal swinging of the disk-in rocker arm and the disk-out rocker arm relative to the shell, and the lateral displacement of the holding rod and the driving block relative to the shell, and limit the vertical swinging of the core base. Moreover, the power source for each linking rod is from a simple longitudinal displacement of the slider driven by an actuating device. Thus, the present invention can not only use simple members to complete the purpose of conveying an optical disk, but also achieve cost reduction and light/slim/short/compact shape design concept.
