ABSTRACT:
An optical data recording/reproducing apparatus includes a light-receiving unit for receiving a light beam which has passed through or is reflected by a recording medium, the light-receiving unit having a plurality of light-receiving areas which are disposed such that they can perform wavefront splitting on the single light beam when the light-receiving areas receive the light beam, a data signal sensing unit for obtaining a data signal on the basis of an output of at least one of the plurality of light-receiving areas, and a servo signal sensing unit for obtaining a servo signal on the basis of an output of at least one of the plurality of light-receiving areas. The light-receiving area used to obtain the data signal and the light-receiving area used to obtain the servo signal are different from each other.
