A method for determining a loading status of a disk on a round roulette utilizes a pulse signal to control the position of the round roulette. In the method, the pulse signal includes start/end codes, a first and a second identification pulse(ID-1, ID-2) and a disk loading detection pulse(DLDP), wherein the start/stop codes, the ID-1 and ID-2 is used for controlling the position of the round roulette and the DLDP is used for detecting the disk loade on the round roulette. In the inventive disk changer includes a function for detecting whether a disk is adequately loaded on a specific receiving plane of the round roulette or not. This is achieved by comparing a first time period between the falling edge time of an ID-1 and the rising edge time of a DLDP with a second time period between the falling edge time of the DLDP and the rising edge time of an ID-2, thereby allowing the disk changer to check an adequate loading of the disk on a round roulette.
