Abstract:
A data reproduction method and apparatus reads the tracks of an optical disk by means of a read unit having a plurality of optical beams. The method includes a first reproduction step for simultaneously playing back a first plurality of tracks on a disk using the plurality of optical beams; a first jump step for jumping a greater number of tracks than the number of optical beams in a forward direction; a second reproduction step for simultaneously playing back a second plurality of tracks on the optical disk using the plurality of beams after the first jump step; a second jump step for jumping a greater number of tracks than the number of optical beams in a backward direction opposite to the forward direction; and a third reproduction step for simultaneously playing back a third plurality of tracks on the optical disk using the plurality of optical beams after the second jump step.
