Title:
【発明の名称】レーザディスク再生装置のリードイン時間短縮方法
Document Type and Number:
Japanese Patent JP2737866
Kind Code:
B2
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. Thus, the lead-in time which is completed before searching the location of the substantial program to be reproduced after the power is turned on, can be reduced as compared with the conventional technology.
