Filed: 2001-12-27
Abstract: PURPOSE: A method for identifying an optical disk and a method for controlling a focus using the same are provided to strengthen the play function of a set by preventing a disk detection error and a focus on error. CONSTITUTION: An interval counter and a focus OK number counter are cleared(S100). A pickup is descended for a predetermined time before a focus lens is ascended(S110-S120). The interval counter is started for increasing an interval counter value(S130). A focus OK signal is detected during the ascension of the focus lens(S140). If the focus OK signal is not detected, it is judged whether a preliminarily decided predetermined time has passed(S170). If so, the increased interval counter value is stored until the focus OK signal is detected, and the interval counter is cleared, and then the count value of the interval counter is increased and the focus OK number counter is increased by 1(S150). A focus control signal value and a reflective peak value are detected and stored at a point that the focus OK signal is detected(S160). After a predetermine time passes, a disk is identified by using the detected values(S180).
