Abstract
A random access control method is provided, implemented in an optical disc drive for recording data to an optical disc. In the optical disc drive, a buffer stores a plurality of write commands each associated with a data block bound to a destination address. A processor controls the buffer to build a disc write task from the write commands in which addresses are organized in order. A drive unit is controlled by the processor, performing a recording operation to record the data blocks to the optical disc according to the disc write task; wherein the processor further controls the drive unit to verify the recorded data blocks after completing the recording operation.
