Abstract: A lead-in time reduction system determines if a disk is loaded at the time of turning on an initial focus-on function in a laser disk reproducing apparatus. If it is determined that the disk has been loaded, a pick-up is moved directly to a limit switch-on point using a feed motor only. The lead-in time reduction system includes determining if the disk is loaded by checking whether data is picked-up through the pick-up after the pick-up is located on a focus on point, if it is determined that the disk is loaded in the determining step, controlling the feed motor to move the pick-up directly to a limit switch-on point of the laser disk, and if the limit switch is turned on in the controlling step, reproducing a desired program by using picked-up information after picking up a lead-in region of the laser disk.
