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.
An address search method for use in a disk player for playing an information recording disk (1), said disk player having a pickup (3) and a tracking servo system (9-12), comprising steps of : repeatedly performing a track jump operation by which an information reading light spot of said pickup (3) jumps over a plurality of recording tracks on said recording disk (1) at one time, from a locking state of said tracking servo system (9-12) in which said information reading light spot of said pickup (3) follows a recording track on said recording disk (1); placing said tracking servo system (9-12) in said locking state; comparing a present address obtained from a read output of said pickup (3) with a target address; and repeatedly performing the preceding steps for intermittently comparing the addresses until said target address is exceeded by said present address.
