A focus control device of a optical multi disk player reproduces several kinds of disks in a size such as a compact disk and a video disk, etc. and particularly control a focus distance between the optical disk and a pick-up thereby to prevent a tracking direction deviation of the optical disk and an angle degree deviation between the optical disk and a pick-up. The device includes a motor; a guide support part joined and fixed to a main base; a driving support part inserted into the motor and also set into the main base; an operating support part operating and moving vertically upwards and downwards; and an elastic support part supported elastically on the inside of the operating support part.
