Method for managing disk information in combo device

A method for managing disk information in a combo device is provided to output stored and managed information by the request of a user by storing and managing manufacture identity information, current temperature information of the disk loaded in a tray and a PI(Parity Inner)/PO(Parity Outer) error correction value. A method for managing disk information in a combo device comprises the steps of: reading out MID(Manufacture Identity) information and a serial number of a disk loaded in a tray(S203); sensing current temperature in real time(S205); storing the MID information, serial number, sensed current temperature information, and PI/PO error correction value obtained by OPC(Optimum Power Control) in a storage medium(S207); and outputting the stored MID information, serial number, sensed current temperature information, and PI/PO error correction value when an output signal is applied by an input unit(S209,S211).
