Abstract
A buffer management method is provided. A host issues a read command requesting access for a read data block and a write command requesting recording of a write data block. A write buffer is dedicated to store the write data block. A read buffer is dedicated to store the read data block. The method comprises entering the optical disc recorder into a write loop. During the write loop, the optical disc recorder triggering a write command handling procedure in response to the write command; triggering a read command handling procedure in response to the read command; and triggering a pre-recording procedure to prepare the write data block in the write buffer for recording. Wherein contents between the write buffer and read buffer are exchangeable during the write handling procedure, the read handling procedure or the pre-recording procedure.
