Patent ID: 7319646

Claim:
An optical disk device comprising: rotating means for rotating an optical disk; motor control means for controlling a number of revolutions of the rotating means; focusing means having a lens to read a signal which is recorded in a recording layer of the optical disk; servo control means that performs a focus pull-in operation based on a focus error signal and a tracking error signal which are obtained from the focusing means thereby to control a position of the lens; memory means having a data table in which initial values and correction values of a plurality of adjustment items including a rotational speed of the optical disk, a moving speed of the lens and the amount of movement of the lens are described; and logic operation means that issues a correction command of the plurality of adjustment items to the servo control means and determines under respective adjustment conditions whether or not the focus pull-in operation is successfully performed and that in a case when it determines that the focus pull-in operation is not successfully performed, changes position of data read from the data table so as to read correction values, newly sets the respective correction values which are stored in the data table in the memory means to the servo control means, sets the correction value of the rotational speed of the optical disk and moving speed of the lens and repeats the focus pull-in operation until it determines that the focus pull-in operation is successfully performed wherein the memory means has a data table in which a relationship between an ambient temperature obtained from temperature detection means and the amount of movement of the lens of the focusing means is described, and the logic operation means uses the amount of movement of the lens corresponding to the ambient temperature obtained from the temperature detection means as an initial value which is set to the servo control means.
