Abstract: A method for splitting signals, an optical pickup unit, and a recording/reproducing apparatus are disclosed. The method of splitting signals includes splitting polarized light into at least one part using a difference in divergence angles from either a recording medium or a near field lens, the polarized light not passing a separation/combination unit but being reflected from the separation/combination unit, the separation/combination unit passing or reflecting the polarized light following a polarized way of reflected light from a recording medium, and generating a Gap Error Signal (GES) corresponding to the at least one part of the polarized light.

Abstract: A method and apparatus for preventing a collision between a recording medium and a lens are disclosed. The method for preventing the collision between the recording medium and the lens includes controlling a gap error signal (GES) between the recording medium and the lens to be maintained at a near field level, detecting a collision between the recording medium and the lens, pulling out the lens from the recording medium during a predetermined time so as to prevent a re-collision between the recording medium and the lens, and re-controlling the gap error signal (GES) between the recording medium and the lens to be re-maintained at the near field level.

Abstract: A recording/reproducing apparatus and a tracking control method which can perform data processing for reliably recording or reproducing data on or from a recording medium are disclosed. Tracking error signal (TE) is generated using difference signal (A-B) produced from reflected light from a recording medium and an offset included in the difference signal is compensated for using another reflected light received separately from the reflected light. Offset-compensated tracking error signal ((A-B)-k(C-D)) is obtained by subtracting another difference signal (C-D) produced from the separately received reflected light according to gain (k) from difference signal (A-B). Different gains may be used for areas on the recording medium having different reflectances. Thus, the tracking error signal can be compensated for an optical offset caused by lens movement and an offset caused by different reflectances and light radiated to the recording medium can accurately follow its track to perform reliable data processing.
