ABSTRACT:
In an apparatus and a method for reproducing recorded signal related to this invention, a dynamic tracking head having two gaps, which deviate from each other traces a single track. Optimum dynamic tracking control is performed using track ID and a differential between envelope signals, which is a signal reproduced from the two gaps, and DC wobbling error. Thus, it controls the position of a reproducing head to a target track position.
