ABSTRACT:
An appropriate track calculation equation is inducted according to a relationship between a storage area and a track pitch of a compact disc, and a pickup unit is instantly shifted to a location calculated with the track calculation equation. Therefore, an error after performing a track jump modulation is reduced to a smallest degree, and in other words, the pickup unit may access a location on the disc currently required by a user without frequent or time-consuming long seeks. As a result, when the pickup unit accesses compact discs having unknown formats, which indicate different capacities or properties, a track error may be calculated in a shortest time so as to shift the pickup unit accordingly and to fix track jumps, and the user may browse any location on the compact discs having unknown formats smoothly.
