摘要： A method for controlling moving time of a sled in consideration of deviation between decks when initializing an optical disk reproducing apparatus. The method includes the steps of: (a) measuring the time required by the sled for traveling a predetermined number of tracks of an optical disk, calculating a one (1) track moving time from the measured time, and comparing the calculated one (1) track moving time with a reference one (1) track moving time; and (b) lowering the voltage applied to a sled motor if the calculated one (1) track moving time is faster than the reference one (1) track moving time, and otherwise increasing the level of the voltage. As a result, the problem of variation in the sled's moving time according to deviation between decks is resolved, and deviation in access time between different decks is reduced, thereby improving the stability and reliability of the system.
