Method for searching identification of disk mounting section in optical disk changer system

A method for searching an identification of a disk mounting section in an optical disk system, said method comprising:

• (i) initializing all data for searching the identification, wherein the all data including a first count value of the identification recognition pulse area, a second count value of the beginning/end pulse area, a third count value of the start/stop-pulse area, a fourth count value of a first logic area, the identification number, logic states of the old and present pulses, an identification recognition signal, and a present identification, the selected identification, and a generating interval of the signal for detecting the identification searching pulse;
• (ii) determining whether a present identification is equal to a selected identification in order to control a driving of a disk which is mounted on the optical disk changer system according to the determination result;
• (iii) determining whether the turntable of the optical disk changer system is rotating in order to control generation of a pulse for searching the identification including an identification recognition pulse area, a beginning/end pulse area, and a start/stop pulse area and control a signal for detecting the identification searching pulse according to the determination result;
• (iv) determining whether the detection signal is generated once two msecs in order to control set values of an interval of the detection signal, an old pulse, and a present pulse, wherein the old and present pulses are respectively pulses which before and at present are detected in the detection signal according to the determination result;
• (v) determining whether the old and present pulses are a low state or a high state in logic;
• (vi) determining whether an identification number is equal to the selected identification in order to determines whether a disk mounting section corresponding to the selected identification is searched when the old and present pulses are a low state in logic, and detecting the identification recognition pulse area, the beginning/end pulse area, and the start/stop pulse area when the old and present pulses are a high state in logic, in step (v).
