OPTICAL DRIVE AND OPTICAL DRIVE CONTROL METHOD

FIELD: information technologies. ^ SUBSTANCE: optical drive contains an objective for converging of a light bunch on an optical disk with a layer for information storage; the executive mechanism for moving the lens perpendicularly to the information storage layer; the executive mechanism control unit for moving the objective with preset speed by means of handling the operation of the executive mechanism; and the device detecting position of a disk and detecting position of the lens when the focal point of a beam is allocated on the information storage layer, as disk position. When the lens moves to a disk for performance of focus search operation, speed of moving the lens is set as high while the lens will not reach a switch point of the speed defined by position of a disk, and is set as low as soon as the lens passes the mentioned point. Thus the switch point is defined on the basis of position of the disk before pergorming focusing. The specified switch point is set further from a disk, than the lens position when the focal point of a beam is allocated on the information storage layer of a disk. ^ EFFECT: increase of usage reliability. ^ 22 cl, 16 dwg
