Abstract
There is provided an optical disc reproducing method capable of reproducing a non-finalized DVD+R. When a seek operation is performed from a present address on the non-finalized DVD+R to an outer circumferential side target address, the outer circumferential direction total jump number of tracks is calculated from a difference between the present address and the target address. When a first condition is satisfied in which the present address is in an inner circumferential zone, the target address is in a second outer circumferential zone, and the outer circumferential direction total jump number is 701 to 2500, the jump number of tracks is set to 340 smaller than the outer circumferential direction total jump number, and a traverse seek using a moving mechanism to move an optical pickup in a radius direction by 340 is performed.
