摘要:
A method of reproducing information recorded on an optical disc having a plurality of recording layers inclusive of a first recording layer and a second recording layer includes the steps of referring to an order of recording of the first recording layer and the second recording layer according to which information is recorded in a prerecorded area of the optical disc, and selecting a scan path in response to the order of recording, from a first scan path including no seek operation preceding a focus jump and a second scan path including a seek operation preceding a focus jump, to scan an optical spot from a first address in the first recording layer to a second address in the second recording layer through scanning along the prerecorded area in at least one of the first recording layer and the second recording layer.
