A method and an apparatus for reproducing data are provided to detect data effectively which is reproduced continuously by obtaining images at the optimum point. An apparatus for reproducing data comprises a beam source(10), an actuator(20), an image sensor(18), a photo detector(19), and a control unit(14). The actuator includes a reflection mirror projects a first beam emitted from the beam source to a recording medium. The image sensor receives reproduction beam diffracted from the recording medium. The photo detector detects the reproduction beam projected to the image sensor. The control unit controls image obtaining of the image sensor according to signal output of the photo detector.
