Title: Method of searching an optical disk
Inventor: JIN CHEOL
IPC: G11B7/004
Filed: 2002-11-14
Abstract: PURPOSE: A searching method on an optical disc is provided to prevent the movement to a wrong address even though addresses of a management area and a program area are overlapped in a large-scaled disc. CONSTITUTION: A searching method on an optical disc includes the steps of carrying out an initial disc loading mode as an optical disc is inserted(S10,S11), and carrying out optimum power calibration for recording user data as a writing command is input from an external host during a standby state(S12,S13). An optical pickup is moved to a target position by driving sled driving/servo part(S14). In order to recognize a current pickup position, a microcomputer recognizes a time code in an ATIP frame output from an ATIP decoder and checks whether a value of the time code is an overlapped value between a management area and a program area. If not(S15), the pickup is moved to the target position(S15-1). If an overlapped time code value is detected(S15), the microcomputer checks whether the area is of the management area or the program area according to a cycle of a frame synchronizing signal-the cycle of the ATIP frame output from the ATIP decoder(S16). In the case of the program area, the microcomputer makes the optical pickup jump long inside but carries out fine search operation in the other case(S17). As the time code is overlapped, the position is determined to be the management area or the program area and moving the optical pickup inward or outward according to the determined area, thereby moving the optical pickup to the target position.
