ABSTRACT:
Address search method for use in a disk player repeatedly performing a track jump operation for jumping over a plurality of recording tracks at one time. The present method changes to a jump state from a locking state in which a tracking servo system of the disk player is locked so that an information reading light spot of a pickup of the disk player follows a recording track. Subsequently, a present address obtained from read output of the pickup is compared with a target address and the tracking servo system is placed in the locking state. The preceding steps for comparing the addresses are repeated until the target address is exceeded by the present address.
