Abstract

Abstract The invention provides an address search method for use in a disk player, comprising repeatedly performing a track jump operation for jumping over a plurality of recording tracks at one time, from a state in which a tracking servo system (9-12) of the disk player is locked so that an information reading light spot of a pickup (3) of the disk player follows a recording track. Subsequently, a present address obtained from read output of the pickup (3) is compared with a target address, with the tracking servo system (9-12) placed in the locking state. The preceding steps for comparing the addresses intermittently is repeated until the target address is exceeded by the present address.
