ABSTRACT:
Apparatus and method for playing an optical disc, whereby the apparatus includes an optical disc drive to read data of the disc, in which the data on a previous layer and a subsequent layer is read in an OTP manner. The optical disc drive includes a pick-up module, and a microcomputer to control the pick-up module such that, when a start sector of the subsequent layer is located outward from a last sector of the previous layer, the pick-up module is moved to a position corresponding to the start sector of the subsequent layer after completing the reading of the data of the previous layer, and is made to perform a layer jump to the position corresponding to the start sector of the subsequent layer. The apparatus can minimize time delay in the layer jump, and shorten a period of time for the layer jump by shortening a traveling distance of the pick-up module, enabling smooth and continuous reproduction of data.
