Abstract:
1. An apparatus for reproducing recorded signal comprising: a head assembly including a plurality of reproducing heads for each track, said reproducing heads deviating from each other in a track width direction; a driving device for driving said head assembly in said track width direction; and a reproduction signal processor for detecting track identification information of a traced track according to a reproduction signal obtained by said plurality of reproducing heads for each of said reproducing heads, wherein said driving device drives said head assembly in said track width direction using said track identification information and said plurality of reproducing heads trace a target track, wherein said driving device wobbles said head assembly at a predetermined amplitude in said track width direction; wherein said reproduction signal processor generates envelope signals for the reproduction signals obtained by said plurality of reproducing heads; and wherein, after driving said head assembly in said track width direction using said track identification information, said driving device further drives said head assembly in said track width direction to eliminate a wobbling error detected using said envelope signals.
