摘要： 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.

摘要： An apparatus for recording/reproducing data using holography technology and a method of reproducing data using the same are disclosed. The recording/reproducing apparatus includes an optical path adjuster which adjusts the path of light emitted from a light source and irradiates the light to a predetermined position of a recording medium, a light reflecting unit which reflects the light transmitting through the recording medium to the predetermined position of the recording medium, an image sensor which receives the reflected light and reproduces data included in the reflected light, and a light receiving unit receiving light, which is not transmitted through the recording medium and is diffracted from the recording medium, and generating a monitoring signal. Accordingly, it is possible to provide a simple optical system suitable for the recording/reproducing apparatus using the holography technology and an efficient method of reproducing data using the same.
