Abstract
A data managing method for an optical disc drive writing data into an optical disc having defects is provided. The optical disc has a user data area and a spare area. The optical disc drive includes a first buffering space and a second buffering space. The data managing method includes: when the first buffering space receives a data corresponding to a defect, not suspending the first buffering space from receiving the user data, and transferring the data, corresponding to the defect and in the first buffering space, to the second buffering space; and when data amount in the second buffering space reaches a predetermined value, suspending the optical disc drive from writing data in the first buffering space into the user data area, and driving the optical disc drive to write data in the second buffering space into the spare area.
