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